Unsafe Condition
Cracks in the radius of the milled section of the nose gear strut attachment bolt in nose gear forks, which could lead to failure of the nose gear structure.
AI-generated summary from the source AD text. Verify against the official source before acting.
Required Actions
Inspect the nose gear fork for cracks using dye penetrant or equivalent nondestructive inspection method. Replace cracked parts with specified nose gear forks (P/N 0442503-497, 0543043-497, or 0543043-498 or newer). Replace earlier type forks on airplanes with 1500+ total hours time in service by first 300 hours thereafter.
AI-generated summary from the source AD text. Verify against the official source before acting.
Compliance Time
On or before January 1, 1972, and thereafter at intervals not to exceed 100 hours' time in service from the previous inspection, or following severe nose wheel shimmy and/or hard landings. For airplanes with 1500+ hours as of January 1, 1972, replacement must occur within the first 300 hours time in service thereafter.
AI-generated summary from the source AD text. Verify against the official source before acting.
Affected Aircraft
Cessna Models 150, 172, 175, and 182 series airplanes with 1000 or more hours' time in service and earlier type nose gear forks (excluding those with P/Ns 0442503-497, 0543043-497, 0543043-498, or newer forks from 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.
