Narrative:
AAIB investigation to Piper PA 24, N7456P: Substantially damaged due to landing gear collapsed on landing after experiencing unexpected windshear, Retford (Gamston) Airport, Gamston, Bassetlaw, Nottinghamshire, 21 July 2017. The incident was the subject of an AAIB Investigation, and the following is an excerpt from the AAIB Report:

"The aircraft departed Leeds East Airport and flew to Retford (Gamston) Airport, where the pilot intended to execute a touch-and-go landing, before returning to Leeds East. His passenger, in the front right seat, was a qualified Federal Aviation Administration Flight Instructor who was observing the pilot for the purpose of a Flight Review, in accordance with Federal Aviation Regulations.

Before departure the pilot obtained a forecast surface wind for Retford which was from 180º at 14 kt. The flight proceeded in a southerly direction at heights between 1,000 ft and 2,000 ft agl and light to moderate turbulence was experienced.

Prior to landing at Retford (Gamston) Airport the wind was reported to be from 160º at 10 kt, with no associated warnings of possible turbulence or windshear.

As the asphalt Runway 21 was in use, the pilot approached using an intermediate flap setting (two stages of flap) and increased the airspeed slightly to allow for the crosswind component. The instructor confirmed that the approach appeared to be “fairly stable”, with the landing gear down and flaps set, until approximately 100 ft agl when he noticed the airspeed temporarily reduce by approximately 10 kt. The pilot recalled that the turbulence increased at this height and that he felt the aircraft sink, but that he was able to correct for this.

Then, at approximately 20 ft agl, he experienced further sink which he attempted to correct by increasing the power, but the stall warner sounded and he responded by pushing forward on the control column. However, he was unable to escape the down draughting air and the aircraft struck the runway “fairly hard” and nose first.

According to the passenger, the nose landing gear collapsed on impact and the aircraft skidded along the runway with the propeller striking the surface and causing the engine to stop. The main landing gear collapsed before the aircraft came to a halt. The pilot then turned off the master switches and the fuel while the passenger opened the door and moved the mixture control to cut off. The two occupants evacuated the aircraft without injury, prior to the arrival of the airport’s rescue service".

=Damage Sustained to airframe
Per the above AAIB Report "Landing gear collapsed causing damage to underside panels and propeller; engine shock-loaded". The 1961-built aircraft was repaired and returned to service
