Airworthiness Directive 2009-06-10
recurringAirworthiness Directives; Boeing Model 727-100 and 727-200 Series Airplanes
What this AD requires
We are adopting a new airworthiness directive (AD) for certain Boeing Model 727-100 and 727-200 series airplanes. This AD requires repetitive internal and external high frequency eddy current, mid frequency eddy current, low frequency eddy current, and magneto optic imaging inspections to detect cracks, corrosion, delamination, and materials loss in the lower fastener row of the lower skin and the upper fastener row of the upper skin, and corrective actions if necessary. This AD results from a report of decompression in a Boeing Model 737 airplane at flight level 290. We are issuing this AD to detect and correct scratches and excessive reduction in material thickness from excessive blend-out or corrosion, which could lead to premature cracking in the lap joint. Such cracking could adversely affect the structural integrity of the airplane.
Which aircraft AD 2009-06-10 applies to
Applies to airplanes identified in Boeing Alert Service Bulletin 727-53A0223, dated March 28, 2002.
Whether AD 2009-06-10 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.
