What this AD requires
This amendment adopts a new airworthiness directive (AD), applicable to certain McDonnell Douglas airplane models, that requires an inspection of the retract cylinder support fitting and the cylinder bore of the support fitting of both main landing gear (MLG) for corrosion, and corrective action if necessary. This action also requires replacing cadmium-plated retract cylinder support bushings and bearings of both MLG. This action is necessary to detect and correct corrosion to the retract cylinder support fitting of the MLG and the cylinder bore in the support fitting, which could result in compromised integrity of the retract cylinder support fitting of the MLG and possible damage to the hydraulic system. This action is intended to address the identified unsafe condition.
Which aircraft AD 04-27332 applies to
Whether AD 04-27332 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.
