Compliance required at 12,000 hours of operation and as indicated below.
As a result of several reports concerning cracks in the main outboard landing gear fitting, the following inspection should be conducted on all Model 240 Series aircraft:
1. Inspect P/N 240-1650716 for cracks running fore and aft on the inboard and outboard face of the fitting, above the fitting boss at the point of tangency of the boss and plate. This inspection must be made at each 1,000 hours of operation following the initial inspection at 12,000 hours.
2. Parts which have cracks not exceeding 2 inches in length may remain in service when properly stop-drilled with a 0.25-inch drill, and inspected daily for further crack progression or other damage.
3. Parts with cracks exceeding 2 inches in length must be replaced with an acceptable part. When replaced with a new part the above inspections are not required until the replacementpart has 12,000 hours of operation, at which time the above inspection procedure, item 1, is again in effect.
