Flight Conducted Under: Part 91: General aviation

Analysis

The pilot departed on a short cross-country flight in the twin-engine airplane. Instrument meteorological conditions (IMC) were present at the time. While en route at an altitude of 3,000 ft mean sea level, the pilot reported that the airplane was "picking up icing" and that he needed to "pick up speed." The controller then cleared the pilot to descend, then to climb, in order to exit the icing conditions; shortly thereafter, the controller issued a low altitude alert. The pilot indicated that he was climbing; radar and radio contact with the airplane were lost shortly thereafter. The airplane impacted a field about 7 miles short of the destination airport. Examination of the airplane was limited due to the fragmentation of the wreckage; however, no pre-impact anomalies were noted during the airframe and engine examinations. Extensive damage to the pitot static and deicing systems precluded functional testing of the two systems.

A review of data recorded from onboard avionics units indicated that, about the time the pilot reported to the controller that the airplane was accumulating ice, the airplane's indicated airspeed had begun to diverge from its ground speed as calculated by position data. However, several minutes later, the indicated airspeed was zero while the ground speed remained fairly constant. It is likely that this airspeed indication was the result of icing of the airplane's pitot probe. During the final 2 minutes of flight, the airplane was in a left turn and the pilot received several "SINK RATE" and "PULL UP PULL UP" annunciations as the airplane conducted a series of climbs and descents during which its ground speed (and likely, airspeed) reached and/or exceeded the airplane's maneuvering and maximum structural cruising speeds.

It is likely that the pilot became distracted by the erroneous airspeed indication due to icing of the pitot probe and subsequently lost control while maneuvering.

Probable Cause and Findings

The National Transportation Safety Board determines the probable cause(s) of this accident to be:
A loss of airspeed indication due to icing of the airplane's pitot probe, and the pilot's loss of control while maneuvering.

Findings

Environmental issues Freezing rain/sleet - Effect on equipment
Personnel issues Aircraft control - Pilot
Aircraft Instrument panel - Inoperative
Aircraft Pitot/static system - Inoperative
Aircraft Airspeed - Not attained/maintained

Enroute-cruise Loss of control in flight (Defining event)

On March 17, 2019, about 1745 eastern daylight time, a Cessna 421B airplane, N424TW, was destroyed when it was involved in an accident near Plain City, Ohio. The pilot was fatally injured. The airplane was operated as a Title 14 Code of Federal Regulations Part 91 personal flight.

The pilot departed on a short cross-country flight. A review of radar and radio communications information revealed that the pilot contacted air traffic control at 1717 shortly after takeoff from James M. Cox Dayton International Airport (DAY), Dayton, Ohio. At 1729, the pilot was given a frequency change. The pilot checked in on the new frequency and requested the RNAV runway 28 approach at
Delaware Municipal Airport (DLZ), Delaware, Ohio, located about 55 nautical miles east-northeast of DAY. About 2 minutes later, the controller advised the pilot of weather ahead, and the pilot accepted a 15° course deviation. At 1735, the controller issued the pilot a heading of 090° and instructed him to maintain an altitude of 3,000 ft mean sea level (msl), which the pilot acknowledged. About 1 minute later, the pilot reported that the airplane was "picking up icing" and that he needed to "pick up speed." The controller issued the airplane a descent to 2,500 ft and subsequently asked if the airplane was clear of clouds; the pilot replied, "negative." About 1739, after noting that the airplane was climbing, the controller cleared the pilot to an altitude of 6,000 ft and approved deviations to the left or right as needed; the pilot acknowledged. The controller subsequently issued the pilot a low altitude alert, and the pilot advised that he was climbing. About 1740, the controller asked the pilot to report his altitude, as altitude information from the airplane was no longer being received; there were no further communications from the accident airplane.

A review of recovered data from onboard avionics indicated that, about 17 minutes after takeoff, the airplane's indicated airspeed began to decay while its groundspeed, as calculated from position information, remained steady. About 1 minute later, fuel flow increased from 38 gallons per hour (gph) to 60 gph, consistent with an increase in engine power. At this time, the indicated airspeed had decayed to about 100 knots (kts), while the groundspeed remained about 150 kts. For the final approximate 2.5 minutes of the flight, the airplane was in a left turn. The airplane entered a climb to about 3,500 ft msl, then began descending around 5,000 ft per minute. The data recorded "SINK RATE" and "PULL UP PULL UP" annunciations, and the airplane's rate of descent was arrested about 300 ft above ground level (agl). The airplane subsequently entered two additional sets of climbs and descents, receiving the same annunciations; however, the pilot did not recover from the third descent. During this time, the airplane's groundspeed, and likely airspeed, exceeded the airplane's maneuvering speed (Va) of 150 kts, and during both the first and final "SINK RATE" annunciations, the airplane's groundspeed exceeded its maximum structural cruising speed (Vno) of 200 kts.

Wreckage and Impact Information

Crew Injuries: 1 Fatal 
Aircraft Damage: Destroyed
Passenger Injuries:
Aircraft Fire: None
Ground Injuries: N/A
Aircraft Explosion: None
Total Injuries: 1 Fatal
Latitude, Longitude: 40.188331,-83.204444(est)

The airplane impacted a field about 7 miles southwest of DLZ. Ground impact scars and the wreckage were consistent with a left-wing-low attitude at the time of impact. The wreckage path was oriented on an approximate 140° heading. From the initial impact point, the airplane crossed a two-lane road before impacting two wooden utility poles. The main wreckage came to rest at the base of the second utility pole, about 395 ft from the initial impact point. The wreckage path was about 850 ft long and the airplane was highly fragmented along the wreckage path. There was no postcrash fire.

All major components of the airplane were located at the accident site; however, flight control continuity could not be confirmed due to the fragmentation of the wreckage.

The cockpit and instrument panel were extensively impact damaged. The positions of the landing gear and wing flaps could not be determined based on the positions of their cockpit controls.

Both engines had separated from the wings and were located in the wreckage path; the first engine was located near the utility poles. The engine sustained heavy impact damage and the majority of the components were separated from the engine. Due to impact damage, the crankshaft could not be rotated by hand. The camshaft, connecting rods, pistons, and valves were examined either by openings in the case or via borescope examination.

The second engine was located near the end of the wreckage path and also sustained heavy impact damage, with the majority of the components separated from the engine. The crankshaft could not be rotated by hand due to impact damage.

Each engine's fuel system, fuel manifold, fuel pump, fuel nozzles, and fuel screen were field examined and no pre-impact abnormalities were noted. The top set of spark plugs were removed from both engines and displayed normal combustion and wear signatures.

Both engines were equipped with three-bladed propellers, which had separated from their respective engines during the accident sequence. All three blades from one propeller were separated from the propeller hub; two of the blades were located in the first field, with the other blade located across the road in the second field. The blades exhibited similar signatures, including twisting and leading-edge polishing. The second propeller's three blades remained in the propeller hub and also exhibited twisting and leading-edge polishing.

Though the examinations were limited by impact damage, no pre-impact airframe, engine, or systems anomalies, were noted that would have precluded normal operation. The extensive damage to the pitot static and deicing systems precluded any functional testing.

Additional Information

An excerpt from the FAA's Instrument Flying Handbook, FAA-H-8-83-15B, Chapter 4, under "Effects of Icing on Critical Aircraft Systems" states:

In addition to the hazards of structural and induction icing, the pilot must be aware of other aircraft systems susceptible to icing. The effects of icing do not produce the performance loss of structural icing or the power loss of induction icing but can present serious problems to the instrument pilot. Examples of such systems are flight instruments, stall warning systems, and windshields.

Flight Instruments

Various aircraft instruments including the airspeed indicator, altimeter, and rate-of-climb indicator utilize pressures sensed by pitot tubes and static ports for normal operation. When covered by ice these instruments display incorrect information thereby presenting serious hazard to instrument flight.

Medical and Pathological Information

The Montgomery County Coroner's Office, Dayton, Ohio, conducted an autopsy on the pilot. The autopsy noted the cause of death was "multiple blunt force injuries." The FAA Forensic Sciences Laboratory conducted toxicological testing. The specimens were were negative for ethanol and tested-for drugs; the specimens were not tested for carbon monoxide or cyanide.

On March 17, 2019, about 1745 eastern daylight time, a Cessna 421B airplane, N424TW impacted terrain near Plain City, Ohio. The commercial rated pilot, sole occupant, was fatally injured and the airplane was destroyed. The airplane was registered to Classic Solutions, Inc. and operated by Phoenix Test Flight, LLC, as a 14 Code of Federal Regulations Part 91 flight. The flight departed Dayton (KDAY), Dayton, Ohio about 1720, en route to (KDLZ) Delaware, Ohio.

A preliminary review of radio communications revealed the pilot was in contact with air traffic control and there was no record of a distress call. The pilot requested runway 28 RNAV approach at KDLZ. The pilot also reported that he was encountering icing. The controller cleared the flight to 2,500 ft. Shortly afterwards, the airplane made a left turn, and radar and radio communication were lost.

The airplane impacted a rural field about 8 miles southwest of the KDLZ airport. Ground impact scars and wreckage were consistent with a left-wing low impact. The wreckage path was orientated on about a 140-degree heading. From the initial impact point, the airplane crossed a two-lane road before impacting two wooden utility poles. The main part of the wreckage came to rest at the base of the second utility pole, about 395 ft from the initial impact point. The wreckage path was about 850 ft long with the wreckage highly fragmented along the wreckage path. There was not a post-crash fire.

After documentation of the accident site, the airplane was recovered for further examination.

Matthew Alan Hayden
August 22nd, 1974 – March 17th, 2019

PLAIN CITY — An experienced Air Force fighter pilot from Arizona died Sunday when a Cessna plane he was flying in snowy weather crashed in a field off Route 42 in Union County.

Matthew A. Hayden, 44, of Phoenix, had taken off from Dayton International Airport at 5:17 p.m. and was headed to Delaware Municipal Airport in Delaware County, according to the Union County sheriff’s office.

The Cessna 421B Golden Eagle II was owned by Classic Solutions Company Inc. in Bakersfield, California. Hayden had just picked up the plane at the Dayton airport, Union County Sheriff Jamie Patton said. He said Hayden was flying to Delaware to meet a friend and was expected to move on from there to another destination.

The eight-seat Cessna he was flying went down at 5:42 p.m. near Route 42 between Harriott and Bell roads in Jerome Township, about 7 miles northeast of Plain City and near the Delaware County line. The aircraft broke into hundreds of pieces in the field.

A witness heard the plane descending and then the crash, and called 911 as he headed to the scene. He stayed on the phone as he came upon the wreckage.

Patton said friends of Hayden’s told authorities that he had only recently retired from the Air Force as a lieutenant colonel. Hayden was a 1998 graduate of the U.S. Air Force Academy and a renowned military pilot and flight instructor. He had served as a test pilot in both the F-16 and F-35 fighter jets and had piloted the F-16 in Operation Iraqi Freedom. The public-affairs office at Luke Air Force Base in Arizona, where he last served, said officers who knew Hayden were all saddened by the news Monday.

His list of accomplishments is long, and the Air Force said he had more than 2,500 flight hours in at least 30 types of aircraft. He made his mark as a test pilot in experimental aircraft, and he had been, before his retirement, a commander of the 56th Training Squadron at Luke.

Craig Hatch, an investigator with the National Transportation Safety Board, arrived on the scene about noon Monday. He said it’s too early to say whether the snowy weather on Sunday was a factor in the crash.

Hatch said Hayden reported no problems over his radio before the crash.

Debris stretched across fields on both sides of Route 42. Power poles were also sheared off or otherwise damaged. Route 42 from Route 33 to the Delaware County line was closed until about 4 a.m. Monday for the investigation. The highway was shut off again in the afternoon for about two hours while investigators gathered evidence; it reopened about 3:30 p.m.

Hatch said he hoped to have all the wreckage cleared away Tuesday. He said the full investigation could take a year.

MARYSVILLE, Ohio — Authorities have identified an Arizona pilot who was killed when the small plane he was flying crashed into a farm field in Ohio.

The Union County Sheriff's Office said Monday that 44-year-old Matthew Hayden, of Phoenix, died Sunday night when the Cessna 421B Golden Eagle II crashed off Route 42 near the border of Union and Delaware counties.

According to Luke Air Force Base, Hayden was a Lieutenant Colonel with the 56th Training Squadron.

Hayden's bio stated he was one of the most experienced F-35 pilots in the world, and has flown and instructed new pilots at Luke AFB since the inception of its program.

Hayden also made history as the first Luke AFB pilot to reach 500 flying hours in an F-35 Lightning II.

Union County Sheriff Jamie Patton says the former Air Force pilot took off from Dayton International Airport on Sunday evening and was headed to Delaware Municipal Airport in central Ohio when the plane crashed shortly before 6 p.m.

Patton says the plane was owned by Classic Solutions Company Inc., out of Bakersfield, California.

An investigator with the National Transportation Safety Board says it's too early to determine what caused the crash.

UNION COUNTY, Ohio — Authorities say one person died when a small plane crashed into a farm field in Union County.

Chief Deputy Tom Morgan of the Union County Sheriff's Office said that the plane skidded across a road and hit a utility pole and lines after crashing Sunday. That caused a power outage in the village of Plain City, northwest of Columbus.

It was snowing and overcast at the time of the crash. The plane was identified as a Cessna 421C Golden Eagle. Chief Deputy Morgan said it was "totally destroyed."

The sheriff's office identified the deceased pilot as 44-year-old Matthew A. Hayden, of Phoenix, Arizona.

The cause of the crash is unknown. The Federal Aviation Administration and the National Transportation Safety Board are assisting in the investigation.

MARYSVILLE, Ohio (WSYX/WTTE) — A man was killed when a Cessna 421 twin-engine airplane swung low over rural Union County on Sunday, violently crashing into utility poles along Route US-42. The victim was later identified as 44-year-old Matthew Hayden of Phoenix.

The crash left a debris field stretching 400 yards wide on either side of the roadway, according to the Union County Sheriff's Office.

"(The plane) is totally destroyed. Literally, hundreds of pieces everywhere," said Chief Deputy Tom Morgan. "When it crashed into the farm field, it continued across US-42 and struck utility poles and utility lines."

The crash shattered at least one pole and brought down wires, leading to widespread power outages. Morgan said that most Ohio Edison customers in Plain City were impacted. An outage map for Union Rural Electric Cooperative showed about 2,500 more customers without power in Jerome Township and Concord on Sunday evening.

The Federal Aviation Administration joined the investigation Sunday night, which will aim to determine where the aircraft originated from and where it was headed.

During the time of the crash, Union County was swathed in a small but intense band of snowfall that made for whiteout conditions on local roadways at times. Morgan said further snowfall after the crash had hampered the early stages of the investigation, as debris quickly became covered with snow.

Only one witness is known to have heard the crash, according to Morgan. Any other witnesses are asked to call the Union County Sheriff's Office at (937) 645-4110.

  1. I feel badly for these folks.

    Today I was flying the PA-28R-180 southeast out of Chicago and nearly got to Lafayette IN and realized the snowstorm had broadened in front of me. I dropped down in an open slot from 9500 feet (VFR over the top) and realized the was broken scud down to 200' and the windmill rotors were topping into the scud base. I looked for a rural runway and could not even see it from 1200' up.

    It was time to get out of there and ended up climbing back up on top and flying 75 nm west to Bloomington IL to find VFR to the ground, a snow cleared runway and good overnight accommodations.

    I decided to break the accident chain. Tonight i had a good meal in a hotel restaurant.

    I only wish these folks who perished would have done the same.

  3. Very easy to get vertigo when flying thru falling snow, must stay very focused on instruments and turn outside lights off.

  4. Another case of spatial disorientation in IMC in a piston-twin. Same ending as the Yorba Linda crash but without ground fatalities. You can see his FlightAware flight track where he starts to lose it and enters a graveyard spiral. Sad ending to the pilot & plane.

  5. Sounds like you got luckIer that the guy in 421c. I prefer reading about this than participating.

  6. This happened a few miles north of my house. Weather was absolutely horrible with heavy snow and minimal visibility. Hugely challenging for a GA aircraft trying to land. I believe the pilot was military or ex-mil out of Luke AFB in PHX if bio is correct. Very sad .. RIP.

    ReplyDelete
  7. I believe every C421 came with an autopilot. If you get spatial disorientation turn the a/p on and get your head together; unless of course the autopilot was inop.

  8. Just because you're instrument rated and have a capable all-weather plane doesn't always mean you have to launch into known bad weather. Sometimes you have to say I'll wait until better weather and fly another day. The pilots I know say if you positively have to be somewhere take a commercial airline flight and let the pros handle it.

    ReplyDelete
  9. I listened to archived atc for this flight, first thing that caught me attention was his read back of atc clearance, only read back squawk code, to cool to read it all back, bad sign. Next when he switches to dep the controller keeps questioning altitude and headings, guy was in trouble 5 minutes after takeoff, I know his bio reads of f-16 and f-18s and lots else in that line up, over 25o0hrs tt, instructor pilot, however, a 1973 Cessna 421 is not for someone not really current in it, not to mention the ifr conditions.Some higher time/jet pilots tend to treat these type and conditions below us, because we fly big fast jets, single pilot hard ifr is harder then flying your f16 around.

    USAF recently retired Lt. Col.
    F-35 Instructor / Test Pilot .. one of the highest time F-35 jockeys on earth
    hard to believe such a thing could happen with a world class decorated pilot such as he but the conditions were indeed very bad yesterday evening
    I guess gravity and the elements give no one a pass :(
    RIP Col. .. and thank you for your service

  11. How many hours / experience did he have on the C421 or GA aircraft in general?
    How familiar was he flying GA aircraft in bad weather / IMC?

    Mil jet hours do not count in this environment.



    ReplyDelete
  12. First, it was a '74 421B model (not C) with tuna tanks. 2nd, Mil flying (high-performance jet) is totally different than GA, especially piston GA. 3rd, pitot-tube icing (should tell by switch position), alternate air (not sure if this is applicable)? 4th, autopilot? 5th, higher altitude (3000msl, ~1900agl) - true it's a 65-mile flight, but I'd be thinking at least FL050 depending on the ceiling, layers, wind (IMHO). 6th, squawk readback only (according to another person)? 7th, ~5:30pm departure couldn't wait 'til first-thing the next morning (firsthand - it was snowing HARD around this time). 8th, were boots activated, were they working? 9th, was KDLZ WX even legal for VOR/GPS approaches, wx was near zero-zero white-out (from personal observation) on I-71 (10sm east). 10th, hours in type, training, last flown, etc. Lastly, this post isn't to cast aspersions nor be critical, just the first questions I'd be asking. Thoughts and prayers with family, and thanks (as a fellow former Air Force officer) for his service.

  13. Break the accident chain? Not really understanding that comment. Should have said, “got lucky” as stated following comments.

  14. PS - forgot to mention aircraft airworthiness condition - #11 aircraft maintenance history, inspections, TT, SMOH (motors & props), AD's, corrosion (I believe there's a major AD for spar corrosion), etc.

    ReplyDelete
  15. Tuna tanks are the earlier tanks, never put onto the 421 series. Early 310 tanks as well as early 320.

    Just don't want anyone to get embarassed at the coffee pot at the FBO!

    ReplyDelete
  16. 2000ft altitude excursions, ground speed varied from 60 to nearly 300mph, aircraft WAS
    stalled at apex, 4000+ feet, maybe a stall spin roll......he was either dead or totally incapacitated......I wouldn't rule out a disconnected elevator trim pushrod. See the "AD"? Pilot was alone, forward cg = lots of stress on the trim tab. Notice he steers SE thru a gap in weather...observe the BOW ECHO weather event. Sh*t hits the fan when he penetrates the gust front? Just observations.

    ReplyDelete
  17. For an anonymous poster who hangs out at the FBO coffee pot.. you should spend more time in research and less time drinking coffee. 1974 C421B had tip tanks just like the C310 and C320 (tuna tanks). Later models of the C421 went with the straight wing.

    ReplyDelete
  18. The 421 never had "Tuna Tanks". It had tip tanks, yes. The tunas where roundish and didn't look very aerodynamic. The later tanks had a nice looking profile.

    ReplyDelete
  19. my apologizes to any I may have offended. I had completely forgotten the difference between the "tuna tank" (like on Sky King's 56 C310 and the tip tanks on the early C421, which were the more aerodynamic version.

    ReplyDelete
  20. actually , upon doing my research, the first Sky King 310 was a 1957, C310B.

  21. Looking at the tracker, it looks like he hit the front of the squall and encountered severe turbulence with altitude variations +/- 500 ft. or more. The updrafts dropped his airspeed and a stall in IMC with ice accretion to boot (no pun intended) and steep bank angles made recovery unlikely. In that type of turbulence, he’d be lucky to be able to read his instruments let alone get any useful info from them even if he could.

  22. The comment about only reading back the squawk code needs some context. The controller cleared the pilot "as filed." If the flight is cleared in such a manner there is no need to read the entire course back to the controller. In fact, it's far more succinct to simply read back the squawk code because that's the bit of information the pilot wouldn't have before getting a clearance.

    The pilot mentioned icing but the 421 can handle ice pretty well, assuming anti-ice was selected and pitot head was on. If the pitot iced up that could lead to some weird speed indications and could make flying in IMC challenging. It really does look like a graveyard spiral from the flight track. It's too bad, the pilot seemed like a well accomplished guy.

  23. Doesn't matter how much experience or TT you think you have this is another example of a very good pilot crashing again. Look at the weather with the NTSB the very next day.....pretty nice.... should have found another alternate airport with better weather and spent the night. (hindsight 20/20)
