Airworthiness Directive E6-12825
one-timeAirworthiness Directives; Boeing Model 737-700 and 737-800 Series Airplanes
What this AD requires
The FAA is adopting a new airworthiness directive (AD) for certain Boeing Model 737-700 and 737-800 series airplanes. This AD requires performing a one-time high frequency eddy current inspection for cracking of the backup intercostals located above the cutout for the forward airstair door; doing related investigative and corrective actions if any crack is found; and doing other specified corrective actions if no crack is found. This AD results from a report of fatigue cracks discovered during a full-scale fatigue test conducted by the manufacturer. We are issuing this AD to detect and correct such cracking, which could result in more extensive fatigue cracking and lead to possible loss of cabin pressure.
Which aircraft AD E6-12825 applies to
Whether AD E6-12825 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.
