REGULATORY TEXT:  
62-09-02 R1 CANADAIR: Amdt. 430 Part 507 Federal Register April 25, 1962. Applies to all Model CL-44D4 aircraft equipped with Rolls Royce Tyne Engines.

Compliance required within next 15 hours' time in service and at each 15 hours' time in service thereafter.

To preclude further cases of bearing failure inspect the magnetic plug and the filter in the scavenge oil line from the high pressure turbine bearing for deposits of hard carbon as specified in the note under paragraph 2B of Rolls Royce Tyne Alert Service Bulletin No. A.Ty.79-12. The engine is to be removed from service and repaired in accordance with approved maintenance procedures if such deposits are present.

Upon request of the operator, an FAA maintenance inspector subject to prior approval of the Chief, Engineering and Manufacturing Branch, International Division, may adjust the repetitive inspection intervals specified in this AD to permit compliance at an established inspection period of the operator if the request contains substantiating data to justify the increase for such operator.

(Rolls Royce Tyne Alert Service Bulletin No. A.Ty.79-12 dated March 30, 1962, covers this same subject.)

This directive effective upon publication in the Federal Register for all persons except those to whom it was made effective immediately by telegram dated April 6, 1962.

Revised May 2, 1962.
