What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
On June 8 around 1300 hours FAA was notified, incident occurred around 0846, a Piper PA-44-180, privacy data omittedat unexpectedly experience a l.h. landing gear collapse while conducting training at Pahokee FL Palm Beach County Glades Airport. The incident occurred at the beginning of runway 18 about 150 ‘from the start of the runway and runway numbers.
The flight was conducted under a 14 CFR 61 the PIC is a MEI and the student is a commercial multi engine, the aircraft suffered damages as follow; LH wing lower structure at landing gear area, LH wing pitot static surrounding structure, LH aileron and flap brackets, LH te flap, complete LH landing gear, LH engine sudden stop, LH prop, LH wing tip., noticed stress point at hole where strut attaches to yoke by bolt at bottom, strut was able to be move freely inside housing as design, torque links separated due to a heavy stress but found stress mark at breaking point of strut with what looks like old crack developing due to grease and corrosion on breaking point at the bolt hole bottom of strut, we recommended further evaluation on a laboratory test.
As per PIC statement.
“Before the takeoff, while holding short, we briefed the takeoff procedure and what I was going to do. I told my student power idle, brake evenly to maintain centerline. We used all available runway. Stopped, applied 2000 RPM, verified all engine instruments were in the green. Once we did that my student applied full power. As soon as he applied full power (no airspeed alive callout was made) I cut the right mixture, and immediately rose it right back to full mixture. Will brought back power to idle completely and tried to maintain centerline. When that wasn't working, I jumped on controls and verified power was idle. There was left rudder deflection but we still went to the right of the runway. After getting out to inspect the aircraft we saw the left main gear collapsed behind the engine nacelle before it reached the grass.”
