Airworthiness Directive 97-22-02
recurringAirworthiness Directives; Pilatus Britten-Norman Ltd. Models BN- 2, BN-2A, BN-2B, and BN-2T Series Airplanes
What this AD requires
This amendment adopts a new airworthiness directive (AD) that applies to Pilatus Britten-Norman Ltd. (PBN) BN-2, BN-2A, BN-2B, and BN-2T series airplanes. This action requires modifying the upper engine mounting brackets on the wing front spar as terminating action for the repetitive inspections that were required in AD 84-23-06. AD 84-23-06 is being revised in a separate action, deleting the Pilatus BN-2, BN- 2A, BN-2B, and BN-2T series airplanes from its applicability. This AD is prompted by several reports of cracks in the upper engine mounting brackets and a new terminating action to eliminate the repetitive inspections for Pilatus BN-2, BN-2A, BN-2B, and BN-2T series airplanes. The actions specified by this AD are intended to prevent the failure of the upper engine mounting brackets on the wing mounted engines, which could possibly cause structural failure of the airplane.
Which aircraft AD 97-22-02 applies to
Specific serial applicability list is in the preceding applicability provision, not present in this excerpt. Addresses cracking/wear of the upper wing-mounted-engine mounting brackets, bolts, and bushes per Pilatus Britten-Norman SB BN-2/SB.61, Issue 5; Modification NB/M/1147 (bracket/bush/bolt replacement) terminates the repetitive inspection.
Whether AD 97-22-02 actually applies to your aircraft (by serial and installed parts) and whether it’s already complied with comes from that aircraft’s records.
How AD compliance is recorded
A valid compliance record (14 CFR 43.9) states:
Tailplate reads a tail number’s logbooks and matches every applicable AD — including this one — to its compliance evidence, with recurring next-due dates computed.
