After touchdown the aircraft bounced back into the air and the pilot then raised the flap to the fully retracted position. The aircraft contacted the runway nosewheel first, bounced again and landed on its nosewheeel for the second time. The nosegear subsequently failed and the aircraft skidded straight ahead and came to rest on the runway. The pilot had been advised by an instructor, on the day he left on this trip, to use an approach speed of 80 knots. However, the Piper Operating Instructions for this aircraft recommends an approach speed of 66 knots. The aircraft was flared at 80 knots and ballooned. The pilot said that he was uncertain about landing at a major airport and apprehensive about this landing because of the possibility of wake turbulence from a Boeing 727, which had departed five minutes previously. This accident was not the subject of an on-site investigation.
