71-22-02 CESSNA: Amdt. 39-1323 as amended by amendment 39-1327. Applies to 150, 172, 175 and 182 series airplanes with 1000 or more hours' time in service with earlier type nose gear fork installed but does not include the above model airplanes installed with nose gear fork bearing P/Ns 0442503-497, 0543043-497 or 0543043-498, or newer nose gear forks identified in current Cessna Parts Catalogues.
Compliance: Required as indicated, unless already accomplished.
To decrease the possibility of failure of the nose gear structure:
A) On or before January 1, 1972, and thereafter at intervals not to exceed 100 hours' time in service from the date of the previous inspection, or at any time following severe nose wheel shimmy and/or hard landings, inspect the nose gear fork for cracks in the radius of the milled section of the nose gear strut attachment bolt using the dye penetrant inspection or equivalent nondestructive inspection method.
B) If cracks are found during the inspections required by Paragraph A, before further flight, replace the affected part with applicable nose gear fork P/N 0442503-497, 0543043-497 or 0543043-498 or newer nose gear forks identified in current Cessna Parts Catalogues.
C) For those airplanes with 1500 or more total hours time in service as of January 1, 1972, and for those airplanes upon the accumulation of 1500 hours total time in service after January 1, 1972, within the first 300 hours time in service thereafter, replace earlier type forks with applicable nose gear fork P/N 0442503-497, 0543043-497, or 0543043-498 or newer nose gear forks identified in current Cessna Parts Catalogues.
D) Upon incorporation of the applicable nose gear fork P/Ns 0442503-497, 0543043-497 or 0543043-498, or newer nose gear forks identified in current Cessna Parts Catalogues, compliance with the provisions of Paragraph A are no longer required.
