Plain English Summary

3/10 complexity

This Airworthiness Directive requires owners/operators of Piper PA32R-300 aircraft (serials 32R-7680001–32R-7780444) to remove both left and right main landing gear side‑brace studs and inspect them for cracks using fluorescent penetrant or magnetic particle inspection. Any cracked stud must be replaced with an approved serviceable part. If the out‑of‑production studs (95299‑00/95299‑02) are found cracked and replaced with the new bracket assembly (95643‑06/07/08/09), no further repetitive inspections are required. Costs and work fall to the aircraft owner/operator.
