Visual meteorological conditions prevailed at the time and a instrument flight rules flight plan was filed. The aircraft received substantial damage and the commercial-rated pilot was not injured. The flight originated at North Myrtle Beach, South Carolina on March 26, 1994, about 0800. The pilot he approached runway 13 at Palm Beach International Airport and landed on the "numbers". The left side of the aircraft dipped after touchdown as if the left main tire was flat. He attempted to level the aircraft's wings. The aircraft bounced into the air and then touched down hard. He pulled off the runway and stopped the aircraft. The left main tire was flat. He then called for assistance. Examination of the aircraft by a aircraft mechanic indicated the left main tire had a large flat spot on it. He stated he was told by an unknown witness that reported observing the landing that smoke came from the left tire on touchdown. ## Aircraft - Registration: [N69978](https://openairdocs.org/deregistered/N69978-2013-05-03), registration cancelled 2013-05-03, S/N 310Q1051, built 1974 (OpenAirDocs) - Reported make and model: CESSNA 310Q - Registry model: [Cessna 310Q](https://openairdocs.org/model/cessna-310q) (registry code 2074242) (OpenAirDocs) - Registry engine: [Continental I0-470 series](https://openairdocs.org/engine/continental-i0-470-series) (registry code 17027, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 310Q1051 - Airframe hours: 6806 - Engines: CONTINENTAL IO-470-VO 260 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Operator: Peter L.
