Location: Franklin, VA
Accident Number: ERA17LA067
Date & Time: 12/10/2016, 1219 EST
Registration: N59JL
Aircraft: MATHIAS LINDA B LIGHTNING
Aircraft Damage: Substantial
Defining Event: Loss of engine power (partial)
Injuries: 1 Serious, 1 Minor
Flight Conducted Under: Part 91: General Aviation - Personal 

On December 10, 2016, about 1219 eastern standard time, an experimental amateur-built Lightning, N59JL, was substantially damaged when it impacted terrain while maneuvering in the traffic pattern at Franklin Municipal-John Beverly Rose Airport, Franklin, Virginia. The commercial pilot sustained minor injuries and the pilot-rated passenger sustained a serious injury. The airplane was privately owned and operated by the pilot as a Title 14 Code of Federal Regulations (CFR) Part 91 personal flight. Visual meteorological conditions prevailed at the time and no flight plan was filed for the local flight which originated about 2 minutes earlier.

The pilot stated that both fuel tanks were filled with 100 low lead (100LL) fuel, then she performed a preflight inspection with no discrepancies reported. After starting the engine she taxied to runway 27, and performed an engine run-up also with no discrepancies reported. During the initial climb when the airplane was at 100 ft above ground level (agl), she felt a vibration which soon stopped. She continued the takeoff and noted that all exhaust gas temperature (EGT) readings were higher than normal, the No. 2 cylinder EGT was over the maximum red line limit, and the airplane had experienced a partial loss of engine power. She kept full throttle applied, informed her passenger of the discrepancy, and turned crosswind. On the downwind legs of the airport traffic pattern, where while maintaining 80 mph, she made a radio call announcing her intention to return. The flight continued in the traffic pattern turning onto the base leg of the airport traffic pattern, and while flying about 200 ft agl, she reduced the throttle to slow the airplane from 80 to 75 mph in preparation to turn onto the final approach leg of the airport traffic pattern. At that moment, the left wing dropped immediately, which she later agreed was consistent with an aerodynamic stall though she did not feel any airframe buffet. The airplane impacted trees while in the left-wing low attitude, and remained suspended in the trees, "…a few feet [off] the ground…." Both occupants exited the airplane and walked to a nearby highway where first responders spotted them, then both were transported to a hospital for treatment of their injuries.

The accident airplane was built at the Lightning factory using "Builder Assist mode" in 2007, and was equipped with a 120 horsepower, Jabiru 3300 engine, which was new when installed. It was also equipped with Genesys Aerosystems IDU-450 primary and multi-function displays (PFD and MFD), and a Grand Rapids Technology (GRT) 6000 engine information system (EIS). It was not equipped with stall warning annunciation, or angle of attack indicator. The pilot/builder reported that it had always been operated using only 100LL fuel and aviation oil. She also reported that in the beginning she did not add any oil additives, but later, "…I started using a product called CamGuard designed to protect the camshaft…." She indicated that she used the "Instruction and Maintenance Manual for Jabiru 3300 Aircraft Engine, JEM3304-3" when performing maintenance on the engine, and section 3.4 of that manual titled "Lubricant" contained no warning or note against using oil additives.

The airplane's most recent condition inspection in accordance with the scope and detail of Title 14 CFR Part 43 Appendix D was completed on September 9, 2016, at airplane total time 291.5 hours. A review of the engine logbook revealed only 1 entry indicating that an oil additive was installed; the entry was dated July 31, 2015. An entry dated August 31, 2016, specified that the results of a differential compression test using 80 psi as a base revealed the No. 2 cylinder was reading 66 psi. The airplane had been operated about 2 hours since the inspection.

According to the builder, the maximum specified cylinder head temperature (CHT) and EGT readings were 392°F and 1450°F, respectively.

The PFD and MFD were read-out by the National Transportation Safety Board's Vehicle Recorder Division and according to the report, a total of about 14 minutes of data was recorded that day at 1 second intervals, of which the last 2 minutes 15 seconds was from the accident flight. A review of the downloaded data revealed that during takeoff the EGT reading for the No. 2 cylinder increased to a maximum of 1,468°F and remained at that value for another 2 seconds, then began to decrease to the last reported value of 631°F. The EGT readings from the remaining cylinders were normal from takeoff until about 47 seconds after the highest reading for No. 2 cylinder, then they also began to decrease. There were no exceedances of CHT for any cylinder.

Examination of the Jabiru 3300 engine was performed following recovery of the airplane by several Federal Aviation Administration (FAA) inspectors. Erosion of the piston of the No. 2 cylinder (left forward) was noted. The spark plugs were inspected and the only reported discrepancy was that the No. 2 cylinder spark plugs were slightly oil fouled. Examination of the No. 2 cylinder induction and exhaust systems revealed no evidence of leakage. The No. 2 cylinder barrel and head, No. 2 piston, piston pin, and connecting rod were retained for examination by the NTSB Materials Laboratory.

According to the NTSB Materials Laboratory factual report, the interior portion of the cylinder head near the intake and exhaust valves contained deposits that were consistent with lead oxides and lead bromide, which form after combustion of tetraethyl lead and 1,2 dibromoethane (anti-knocking and lead scavenging additives in aviation fuel). The cylinder barrel exhibited scars that were consistent with sliding wear from the piston crown and skirt, and the sides of the piston exhibited material loss from wear and material spalling. The piston crown exhibited a rough surface with erosion of the surfaces facing the cylinder head and barrel, with deposits similar to those found on the cylinder head. The report stated that the observed damage was consistent with that caused by pre-ignition. 

Tests And Research

Fueling

According to the facility that supplied fuel, 5 aircraft were fueled from the same source before the accident airplane, and 2 aircraft were fueled from the same source after the accident airplane. There were no fuel reported issues. Postaccident, the specific gravity tested the same as the value when the fuel was delivered.

Preignition

According to Advisory Circular FAA-H-8083-25B, titled Pilot's Handbook of Aeronautical Knowledge, preignition can occur when the fuel-air mixture ignites prior to the engine's normal ignition event and is usually caused by a residual hot spot in the combustion chamber. Preignition causes the engine to lose power and produces high operating temperature and may also cause severe engine damage because the expanding gases exert excessive pressure on the piston while still on its compression stroke.

Jabiru Manuals and Documents, Oil Additive

According to the quality manager of the engine manufacturer, current manuals are available on their website. The Instruction and Maintenance Manual for Jabiru 3300 Aircraft Engine, JEM3304-3 which was utilized by the pilot to perform engine maintenance, dated January 2007, was periodically updated to the final version JEM3304-9, dated April 2011. It was not published since then and was replaced by JEM0002-1, titled Maintenance Manual for Jabiru 2200 Aircraft Engine, Jabiru 3300 Aircraft Engine dated July 2012, and updated through JEM0002-7 dated June 2016, currently published on their website.

The quality manager also indicated that warnings about the non-use of oil additives and/or oil stabilizers are located in several documents including a tag attached to every engine they distribute, in section 1.5.5 of the installation manual, in the warranty exclusions section of the maintenance manual, and also in section 2.14 of the engine overhaul manual.

Section 3.5 titled "Lubricant" and section 6.1 titled "Lubrication System" of a newer version of the Instruction and Maintenance Manual did not contain a warning regarding the use of oil additives or oil stabilizers. The engine maintenance manual (JEM0002-7) which, "…has been prepared as a guide to correctly operate, maintain, and service Jabiru 2200 & 3300 engines" was further reviewed and section 3.8 titled "Lubricant" or section 9.5 titled "Oil & Filter Change" did not contain a warning or caution against the use of oil additives or oil stabilizers.

The engine manufacturer had no information as to what impact the oil additive used would have had on the engine.

NTSB investigators may not have traveled in support of this investigation and used data provided by various sources to prepare this aircraft accident report.

On December 10, 2016, about 1215 eastern standard time, a privately owned and operated experimental amateur-built Lightning, N59JL, was substantially damaged when it impacted terrain while maneuvering in the traffic pattern at Franklin Municipal-John Beverly Rose Airport, Franklin, Virginia. The commercial pilot sustained minor injuries and the passenger sustained a serious injury. The airplane was operated under the provisions of 14 Code of Federal Regulations Part 91 as a personal, local flight. Visual meteorological conditions prevailed at the time and no flight plan was filed for the flight which was originating at the time of the accident.

The pilot stated that she performed an engine run-up before takeoff with no discrepancies noted. During the initial climb when the airplane was at 100 feet above ground level (agl), she felt a vibration which soon stopped. She continued the takeoff and noted that all exhaust gas temperature (EGT) readings were higher than normal, the No. 2 cylinder EGT was over the maximum red line limit, and the airplane had experienced a partial loss of engine power. She kept full throttle applied and informed her passenger that something was not right. She turned crosswind and then downwind, where while maintaining 80 mph, she made a radio call announcing her intention to return. The flight continued in the traffic pattern, and received a terrain warning indicating that the airplane was less than 500 feet agl. She turned onto base leg, and while flying about 200 feet agl, she reduced the throttle to slow the airplane from 80 to 75 mph in preparation to turn onto the final approach leg of the traffic pattern. At that moment, the left wing dropped immediately. She indicated that she did not feel any airframe buffet, and reported the airplane impacted trees while in the left-wing low attitude, and remained suspended in the trees. Both occupants exited the airplane, and were taken to a hospital for treatment of their injuries. Examination of the airplane was pending recovery from the accident site.





FRANKLIN, Va. (WAVY) — Crews responded to an airplane crash that happened Saturday afternoon off the runway in a field near Franklin Municipal-John Beverly Rose Airport.

CARRSVILLE -- The pilot and passenger of a plane that crashed shortly after taking off on Saturday were able to walk away from the scene, according to Virginia State Trooper 1st Sgt. Greg Jackson. 

Linda Mathias of Norfolk, the pilot, and Paul Ruehrmund of Williamsburg were found standing at the back of a residential lot by first responders from the Carrsville Volunteer Fire Department; the call had come in at 12:28 p.m. 


There were apparent only minor injuries, but the two were taken to Southampton Memorial Hospital for further examination. 


A representative there said details of their condition could not be released.


Jackson said that apparently the plane had taken off from the Franklin Municipal Airport. 


The sudden cause of the engine failure is unknown as yet, and the aircraft fell about 100 yards from Walters Highway. 


Trees broke the fall of the plane, which landed tilted to the left. Mathias and Ruehrmund got out and made their way to the road.


There was a small, dripping fuel leak, according to Jackson, and the area was restricted until representatives from the Federal Aviation Administration could inspect the scene.

Linda Mathias, a Windsor native, started her flying career in the late 1960s. In addition to serving as an FAA Designated Pilot Examiner, she also has participated in cross-country races and aerobatic stunt competitions.


Flying over the Smithfield Foods plant in her 1978 two-seater Decathlon single-engine plane, Linda Mathias speaks through her headset.

"When the wind blows the right way, you can smell the ham," she says.

Mathias has been blazing a trail in the sky since 1968, when she was a 27-year-old government civilian learning to fly in the Navy's flying club program.

It wasn't unheard of for women to pursue a pilot's license at the time, Mathias says, but female pilots in the commercial sector, especially, were still a rarity.

"A sailor started telling me about his flying lessons through the club, and I thought 'you can do that?' And that's where it began," she says.

Mathias is selling one of her airplanes — the 1978 Decathlon — in a Memorial Day auction at Phoebus Auction Gallery in Hampton. It's the first airplane the auction house has sold, says manager Bill Welch.

"The great thing about this (auction) business is that you find things that tell the story of how society has changed over the years," he says. "You just can't find these planes made in America anymore."

Welch says he would like to see a bid of $35,000 on the plane, which is known as an aerobatic, or stunt, aircraft.

"This one is a tail dragger. See the wheel at the back of the plane," Mathias says. "It takes more skill to fly those."

Mathias, who recently moved from Windsor to Norfolk, is downsizing her plane collection, which also includes a piper cub from the World War II-era.

When her husband was alive, he died in 2011, the couple would fly and restore classic airplanes together. At one time, they owned anywhere between seven and nine planes, she says. Without her husband around, who was skilled in airplane mechanics, maintenance and repairs are costly.

Mathias, who has seen more than four decades as a female pilot, is a Designated Pilot Examiner for the FAA and the governor — which is like a regional president — for the Mid-Atlantic chapter of The Ninety-Nines, a nonprofit organization for female pilots that promotes aviation education. Amelia Earhart is listed as the organization's first president.

Over the years, Mathias has participated in cross-country races and aerobatic competitions, performing stunts such as loops, rolls, hammerhead dives, inverted flying and other tricks. That part of her flying career was just for fun, she says.

"She has always been an ambitious person in the organizations she's involved in," says Charles Griminger, of Hampton. Griminger is retired from the military and now flies World War II airplanes for the Old Dominion squadron of the Commemorative Air Force, an organization that promotes education about historical military aircraft. The pilots often perform in air shows.

"She's an excellent person," he says.

Mathias, who exudes a combination of no-nonsense efficiency and gentleness, doesn't speak much about the hardships of being an early female pilot. She does admit that she took some serious, and sometimes crude, ribbing from male pilots and instructors in the late '60s and early 1970s.

"I do remember during one lesson the instructor said that he would leave a string for me to follow so I could find my way back," she says.

She smiles about those stories, but her determination to pass on her passion to a younger generation of women is evident.

"I had considered commercial airlines, but you just didn't see very many women then," she says. "They were just starting to break in. You see a lot more women (pilots) in the terminals now."
