Cracks have been found in the nose landing gear actuating cylinder rod end eyebolt, Peacock P/N C50137-2. To assure that all cracked eyebolts are replaced, accomplish either (a) or (b) as applicable:

  (a) If the nose landing gear actuating cylinder rod end eyebolt Peacock P/N C50137- 2, has not been modified in accordance with Convair Service Engineering Report No. 6820-240- 23/340-45/440-45 dated August 24, 1962, or an FAA Western Region, Engineering and Manufacturing Branch approved equivalent modification, within the next 225 hours' time in service after the effective date of this AD, unless already accomplished within the last 775 hours' time in service, and thereafter at periods not to exceed 1,000 hours' time in service from the last inspection, inspect the unmodified eyebolt, where the threaded area is machined for the relief radius, by a dye penetrant method or an FAA approved equivalent method for any indication of cracking. Replace a cracked eyebolt with an uncracked eyebolt, Peacock P/N C50137-2, before further flight and continue the repetitive inspections.

  (b) If the nose landing gear actuating cylinder rod end eyebolt, Peacock P/N C50137-2, has been modified in accordance with Convair Service Engineering Report No. 6820- 240-23/340-45/440-45 dated August 24, 1962, or an FAA Western Region, Engineering and Manufacturing Branch approved equivalent modification, within the next 1,000 hours' time in service after the effective date of this AD, unless already accomplished within the last 4,500 hours' time in service, and thereafter at periods not to exceed 5,500 hours' time in service from the last inspection, inspect the eyebolt, where the threaded area is machined for the relief radius, by a dye penetrant method or an FAA approved equivalent method for any indication of cracking.
