Piper PA-32RT-300T

Analysis

According to the pilot after liftoff the elevator flight control became unresponsive and he could only control pitch with the elevator trim. The pilot flew to Fayetteville Regional Airport where he requested the longest runway for an emergency landing. During the landing flare, the nose dropped when the pilot reduced engine power, and the nose wheel collided with the runway and collapsed. Examination of the airframe revealed that the left elevator cable assembly turnbuckle was corroded and fractured. A review of maintenance records showed that the failed assembly had a total time of 2,633 hours and had been in service for 25 years

According to the pilot after liftoff the elevator flight control became unresponsive and he could only control pitch with the elevator trim. The pilot flew to Fayetteville Regional Airport where he requested the longest runway for an emergency landing. During landing flare, the nose dropped when the pilot reduced engine power, and the nose wheel collided with the runway and collapsed. Examination of the airplane revealed that the wreckage debris was scattered in the immediate vicinity of the wreckage. The airplane came to rest on a 040 degree magnetic heading approximately one third from the runway threshold. Examination of the airframe revealed that the left elevator cable assembly turnbuckle was broken at the MS21260S4LH cable terminal end. The terminal failed in the shank portion beneath the 0.040 safety wire wraps with only the safety wire maintaining the integrity between the turnbuckle assembly and the cable terminal end. The MS21260 flight control cable terminal on the opposite end of the turnbuckle also revealed evidence of corrosion. The Piper Lance II Service Manual states "Check aileron, rudder, stabilator trim cables, turnbuckles, guides and pulleys for safety, damage and operation". The Piper recommended inspection times are every 100, 500, and 1000 hours of flight time. A review of maintenance records showed that the failed assembly had a total time of 2,633 hours but had been in service for 25 years.

Probable Cause and Findings
