Airworthiness Directive 97-19599
recurringAirworthiness Directives; British Aerospace (Jetstream) Model 4101 Airplanes
What this AD requires
This amendment adopts a new airworthiness directive (AD) that is applicable to certain British Aerospace (Jetstream) Model 4101 airplanes. This action requires repetitive detailed visual inspections to detect cracks of the shear cleats of the roller guide structural support of the passenger door, and replacement of any cracked shear cleat with a new shear cleat. This action also provides for an optional terminating modification that constitutes terminating action for the repetitive inspections. This amendment is prompted by a report indicating that fatigue cracking was found in the roller guide shear cleats of the passenger door. The actions specified in this AD are intended to detect and correct such fatigue-related cracking, which could result in structural failure of the passenger door, and consequent rapid depressurization of the airplane or loss of the passenger door while the airplane is in flight.
Which aircraft AD 97-19599 applies to
certain
Whether AD 97-19599 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.
