Compliance required as indicated, unless already accomplished.

To prevent failure of the powerplant hoses carrying air, fuel and/or oil and resultant fire hazard, accomplish the following:

(a) Within 100 hours' time in service from the effective date of this AD, or prior to return to service after the next annual inspection, whichever occurs first, visually inspect the powerplant fuel, air and oil hose assemblies listed in RajayService Letter No. 28 dated August 3, 1981 to determine the general condition and age of the hose assemblies based upon the metal plate attached to the hose, and;

1) If the hose assembly is five years old or older, replace with like serviceable part prior to further flight.

2) If the hose assembly does not have a metal tag and the age cannot be determined, replace with like serviceable part prior to further flight.

3) Record hose ages in the aircraft engine log book and establish a replacement schedule for affected hoses such that a five year life will not be exceeded.

4) If the hose assembly is deteriorated (regardless of age), replace with like serviceable part prior to further flight.

(b) Special flight permits may be issued in accordance with FAR 21.197 and 21.199 to operate aircraft to a base for the accomplishment of inspections or modifications required by this AD.

(c) Alternative inspections, modifications or other actions which provide an equivalent level of safety may be used when approved by the Chief, Engineering and Manufacturing Branch, FAA Western Region.

The manufacturer's specifications and procedures identified and described in this directive are incorporated herein and made a part hereof pursuant to 5 U.S.C. 553(a)(1). All persons affected by this directive, who have not already received these documents from the manufacturer, may obtain copies upon request to Rajay Industries, Inc., 2600 East Wardlow Road, P.O.
