Registration: N167CB
Aircraft: CIRRUS DESIGN CORP SR22
Aircraft Damage: Substantial
Defining Event: Controlled flight into terr/obj (CFIT)
Injuries: 2 Serious
Flight Conducted Under: Part 91: General Aviation - Instructional 

On April 2, 2017, about 1528 Pacific daylight time, a Cirrus Design Corporation SR22, airplane, N167CB, was substantially damaged when it impacted mountainous terrain near Brinnon, Washington. The flight instructor and the student pilot sustained serious injuries. The airplane was operated as a Title 14 Code of Federal Regulations Part 91 instructional flight.

The cross country flight departed from Whidbey Air Park (W10), Langley, Washington, about 1500 with a planned destination of Bremerton National Airport (PWT), Bremerton, Washington.

According to the flight instructor, they had planned a 3-hour instructional flight and planned to accomplish their traffic pattern work at PWT. While enroute, the flight instructor stated that he wanted to show the student "that there was more to flying than just training." In his words "flying was also fun." Subsequently, the airplane was turned west towards a large valley in the Olympic Mountain range. While flying in the valley, the flight instructor stated that he believed their altitude was at least 2,000 ft above ground level (agl) and that no wind or turbulence was present. However, at some point, the pilots realized they needed to climb to avoid terrain and the flight instructor applied full power and pitched the airplane up into a climb. However, he realized that even with these control inputs, the terrain was rising faster than the airplane was climbing. The flight instructor instructed the student pilot to start a right turn. Shortly thereafter, he felt the turn was too slow and just as the student pilot was increasing the bank of the turn, he took control of the airplane. The flight instructor stated that things were happening too fast for him to recover the airplane and he knew that they were going to crash. Subsequently, the airplane impacted terrain.

The accident airplane was equipped with an Avidyne Primary Flight Display that contained two flash memory devices. The flash memodevices were recovered from the accident airplane and sent to the National Transportation Safety Board's Vehicle Recorder laboratory for download. The downloaded files captured the accident flight.

The data started with the airplane flying southwest over Puget Sound, about 1,700 ft mean sea level (msl). At 1518, the airplane turned left to a south-southwesterly heading. At 1520, the airplane turned to the west and crossed the shoreline north of Brinnon, Washington. The airplane then flew along the Dosewallips river valley, about 1,600 ft msl. At 1523, the airplane began a climb and at 1526, the airplane's altitude indicated about 2,407 ft msl. The airplane then turned left to fly along the Hungry Creek valley; however, the terrain continued to rapidly rise in height. Subsequently, at 1528, the data was consistent with the airplane impacting terrain, near 5,400 ft msl. The accident site was in a box canyon with ridgelines present in front and on each side of it, that were between 100 ft to several hundred ft higher in elevation, than the accident site. Further, the terrain at the accident site, was about 2,000 ft higher in elevation, than that of the river valley that was about 1.5 miles below it.

No anomalies in the recorded data from the accident flight would have precluded the normal operation of the airplane. The last recorded information before impact, indicated the engine was at 2,620 rpm, the airplane in about 29° of right bank, and an indicated ground speed of about 81 knots.

The closest official weather reporting location to the accident site was PWT, located about 25 miles southeast of the accident site. However, due to unknown reasons, the PWT station was off line the day of the accident.

The next closest official weather reporting station was from William R. Fairchild International Airport (CLM), Port Angeles, Washington, located about 32 miles north-northwest of the accident site. The CLM weather observation at 1453, was wind from 310° at 9 knots, visibility unrestricted at 10 miles or more, few clouds at 3,100 ft ceiling broken at 4,000 ft, overcast at 6,500 ft, temperature 8° C, dew point 4° C, and altimeter 30.31 inches of mercury.

A review of the weather information revealed that no significant weather was reported or forecast in the accident area around the time of the accident. A high-pressure system was located off the northwest pacific coast. The local weather surveillance radars for the 1 hour period before the accident time, detected no significant weather echoes over the area for that period.

The wind speed near the accident area around the time of the accident was estimated to be from the northwest about 11 knots from the surface to about 2,000 ft msl, with little directional variation with height and with winds increasing with height. At 6,300, ft the approximate height of Mount Christie, located about 13 miles west of the accident site, the wind was from 305° magnetic at 16 knots, and would have resulted in a downslope wind over the accident site.

A turbulence model indicated that above the surface, about 700 ft, there was a strong vertical shear of about 8.1 knots per 1,000 ft, and a high probability of moderate turbulence. No defined mountain wave or orographic type clouds were identified from the period between one hour prior, and one hour after, the accident time.

An AIRMET, valid at the time of the accident, was issued for mountain obscuration, occasional moderate turbulence below 15,000 ft, and icing conditions between 2,000 and 12,000 ft in clouds and precipitation was current in the area at the time of the accident.

Latitude, Longitude: 47.692222, -123.221944 (est) 

The airplane impacted on a mountainous slope of about 45° and came to rest upright. The airplane wreckage showed that the airplane was in a right turn during impact. All major components of the airplane were located at the site. The accident site was located about 13 miles east from the summit of Mount Christie, in snow packed mountainous terrain. Mount Christie is the high peak of the Olympic mountains, in the Olympic State Park in Washington.

A postaccident examination of the airframe and engine did not reveal any anomalies with the airframe or engine that would have precluded normal operation. The Cirrus Aircraft Parachute System was not activated.

Additional Information

The FAA's Aviation Safety Program publication "Tips on Mountain Flying," section on ridge and pass crossing, states that "experienced pilots recommend crossing a ridge line or pass, at the ridge elevation plus at least 1,000 ft. The publication also states, "plan to be at that altitude at least three miles before reaching the ridge."

The airplane's turn performance was evaluated using a performance chart from the Aerodynamics for Naval Aviators, NAVAIR 00-08T-80 publication. Based on 30° of bank, the performance chart indicated that the accident airplane would have about an 1,500 ft turn radius. A review of the accident area indicated only about 1,000 ft between the higher terrain on each side of the airplane, was available to complete a turn away from the high terrain in front of the airplane. Additionally, during the first half of the turn, the terrain continued to rise.

Aircraft: SOCATA TB20
Aircraft Damage: Substantial
Defining Event: Landing gear collapse
Injuries: 1 None
Flight Conducted Under: Part 91: General Aviation - Personal 

On February 25, 2017, about 1115 eastern standard time, a Socata TB20, N2519T, was substantially damaged during a gear up landing at Melbourne International Airport (MLB), Melbourne, Florida. The private pilot was not injured. The personal flight was conducted under the provisions of Title 14 Code of Federal Regulations Part 91. Visual meteorological conditions prevailed and no flight plan was filed for the flight, which departed Key West International Airport (EYW), Key West, Florida, about 1012.

The pilot reported that during his cross-country flight he noticed the alternator warning light flash and the battery began to discharge. He contacted air traffic control, but did not declare an emergency, and began a slow descent while initiating the emergency gear extension. After multiple unsuccessful attempts the pilot performed a gear up landing.

An examination of the airplane by a Federal Aviation Administration Inspector revealed that the main landed gear was extended but not fully locked. The nose landing gear did not extend and remained in the wheel well. Examination of the airframe revealed that the bottom forward bulkhead was damaged during landing sequence. An examination of the nose gear assembly revealed the circlip on the nose landing gear strut was dislodged from the nose landing gear leg assembly, which allowed the strut to extend further than usual. The circlip used to retain the nose gear strut inside the nose gear assembly had paint on the outer portion of the circlip, which should have been fully set inside the groove used to keep the circlip in place. An examination of the circlip groove revealed that it was in serviceable condition with no corrosion or other deformation within the groove. A review of the maintenance records showed that the nose strut was disassembled and repaired on July 15, 2015, and the airplane was completely repainted on April 5, 2016. Further review of the maintenance records revealed that since the disassembly of the nose gear, a total of 75 hours of flight time had accumulated since the maintenance.

According to the airplane's maintenance manual the, nose landing gear strut retaining circlip should have been fully installed in the groove. After it is installed, the landing gear should be rotated several times to confirm proper installation.
