Airworthiness Directive 2010-9521
recurringAirworthiness Directives; Airbus Model A300 B2-1C, B2-203, B2K-3C, B4-103, B4-203, B4-2C Airplanes; Model A310 Series Airplanes; and Model A300 B4-601, B4-603, B4-605R, B4-620, B4-622, and B4-622R Airplanes
What this AD requires
The FAA is correcting a typographical error in an existing airworthiness directive (AD) that was published in the Federal Register on March 11, 2010. The error resulted in an imprecise compliance time in a table. This AD applies to certain Airbus Model A300 B2-1C, B2-203, B2K-3C, B4-103, B4-203, B4-2C airplanes; Model A310 series airplanes; and Model A300 B4-601, B4-603, B4-605R, B4-620, B4-622, and B4-622R airplanes. This AD requires repetitive inspections to detect cracks of the pylon side panels (upper section) at rib 8; and corrective actions if necessary.
Which aircraft AD 2010-9521 applies to
Also applies to Model A310 series airplanes (all A310 variants, no specific series/subtype listed in the text). This document is a correction to AD 2010-06-04 fixing a typographical compliance-time error in Table 1 (>17,500 total flight cycles); it does not change the applicability itself.
Whether AD 2010-9521 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.
