Unsafe Condition
Moisture separator assembly shell failure due to upper shell assemblies P/N 841665 or 841665-01 reaching three years or 20,000 cycles in service, or undetected cracks/corrosion from lack of annual fluorescent penetrant inspection.
AI-generated summary from the source AD text. Verify against the official source before acting.
Required Actions
Inspect moisture separator assemblies P/N 890469, 890469-01, 890469-02, 891572, or 891572-01 for upper shell assemblies P/N 841665 or 841665-01. Replace shell assemblies if in service beyond three years or 20,000 cycles. Perform annual fluorescent penetrant inspection per Walter Kidde Manual F-41024B for those with less than three years or 20,000 cycles. Inspect pre-September 1979 manufactured shells before service.

ADDRESSES: FOR FURTHER INFORMATION CONTACT: SUPPLEMENTARY INFORMATION: REGULATORY TEXT: 82-22-51 FAIRCHILD REPUBLIC: Amendment 39-4543. Applies to Fairchild Republic Models F-27 and FH-227 airplanes certificated in all categories. To prevent moisture separator assembly shell failure, accomplish the following: A. Prior to accumulating 100 landings or within 20 days, whichever occurs first, unless accomplished within the last 12 months, inspect the aircraft's moisture separator assembly P/N's 890469, 890469-01, 890469-02, 891572, or 891572-01, as applicable (two per aircraft), for the following: 1) Any of the above separator assemblies having upper shell assemblies P/N 841665 or 841665-01 which have been in service for three years or 20,000 cycles, whichever occurs first, must be immediately removed from service and replaced with a serviceable shell assembly. 2) Any shell assembly P/N 841665 or 841665-01 confirmed to have been installed less than three years or 20,000 cycles accumulated service, whichever comes first, which has not had the annual fluorescent penetrant inspection of shell assembly specified by the Walter Kidde Maintenance and Overhaul Manual F-41024B must be removed from service for the inspection and overhaul specified. Strict compliance with the crack and corrosion detection criteria of the Walter Kidde Manual is mandatory. 3) Any shell assembly P/N 841665 or 841665-01 with manufacturing dates stamped on the top of the shell housing prior to September 1979 which have never been in service must be inspected in accordance with Kidde Manual F-41024B before being put in service. B. Alternate means of compliance which provide an equivalent level of safety may be used when approved by the Manager, New York Aircraft Certification Office, FAA, New England Region. C. Special flight permits may be issued in accordance with FAR 21.197 and 21.199 to operate airplanes to a base for the accomplishment of inspections and/or modifications required by this AD. This amendment becomes effective February 3, 1983, and was effective earlier to those recipients of Telegraphic AD T82-22-51 dated October 27, 1982. FOOTER:
