Date and Time: March 19, 2022, 15:30 Local
Registration: N42764
Aircraft: Piper PA-28-151 Aircraft Damage: Substantial
Defining Event: Collision with terr/obj (non-CFIT) 
Injuries: 3 None
Flight Conducted Under: Part 91: General aviation - Personal

Analysis

The pilot reported that, he entered a valley and descended to an altitude of about 300 to 500 ft above the ground. As the pilot began a climb to clear an upcoming ridgeline, he realized that the airplane would not clear the terrain despite making S-turns and adjusting to best rate of climb airspeed. Subsequently, he initiated an emergency landing and the airplane impacted terrain in a level attitude, which substantially damaged the left wing and underside of the airplane. The pilot reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.

Probable Cause and Findings

The National Transportation Safety Board determines the probable cause(s) of this accident to be:
The pilot’s failure to maintain clearance from rising terrain while operating in a canyon, which resulted in an impact with terrain

Findings

Personnel issues Decision making/judgment - Pilot
Aircraft Altitude - Not attained/maintained
Personnel issues Monitoring environment - Pilot
Environmental issues Mountainous/hilly terrain - Contributed to outcome

  1. From the ADS-B track here:

    It appears they were maneuvering between 3-4,000 feet in the vicinity of Cuyamaca Peak (SD County's second highest peak at 6512 feet) and they likely got caught in a downdraft or were unable to out-turn and out-climb surrounding terrain. It appears they slowed down to around Vx and were climbing at between 500-700 ft/min right before impact, which is likely why they survived the crash into the brush. Still the occupants are VERY lucky!

    1. "The typical light airplane is designed to provide protection in crash landings that expose the occupants to nine times the acceleration of gravity (9G) in a forward direction. Assuming a uniform 9G deceleration, at 50 mph the required stopping distance is about 9.4 feet. While at 100 mph, the stopping distance is about 37.6 feet—about four times as great." https://www.faa.gov/regulations_policies/handbooks_manuals/aviation/airplane_handbook/media/19_afh_ch17.pdf

    2. The brush/trees would also soften the blows to the body....

  2. Mushing in on the low-height-vegetation of that upslope rising to meet them as speed petered out was a much better option than a stall and plummet impact from failing a turn back that is so often the case in these reports.
