The airworthiness directive

50-29-01 CURTISS-WRIGHT Applies to Model C-46 Series aircraft.

Compliance required within 25 hours' time in service after the effective date of this amendment, unless already accomplished within the last 175 hours' time in service, and at intervals thereafter not to exceed 200 hours' time in service from the last inspection.

Inspect the lower surface of the wing center section for loose rivets (5/32-A17ST modified brazier head) in the area of the front and rear spars between Stations 82.5 and 107.5. If more than 50 rivets are found loose along either the front or rear spar on either R.H. or L.H. wing center section between the stations mentioned above, they should be replaced immediately following the procedure outlined by Civil Aeronautics Manual 18.20-3(e)(4) (ii)(a).

If less than 50 rivets are found loose at any of the above specified locations, the rivets need not be replaced until the time of next major overhaul.

Upon request of the operator, an FAA maintenance inspector, subject to prior approval of the Chief, Engineering and Manufacturing Branch, FAA Southern Region, 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.

Revised December 28, 1964.
