REGULATORY TEXT:  
61-07-01 CONVAIR: Amdt. 272 Part 507 Federal Register April 4, 1961. Applies to All Model 22 (880) Aircraft.

Compliance required as indicated.

Conduct a daily inspection of all foreflaps, P/N 22-18600-5 or -807, left and right, for cracks in the upper surface skin. Particular attention should be given to the mid span area of each foreflap. Except as otherwise provided for in paragraphs (a), (b) and (c), cracked foreflaps must be modified per Convair Service Bulletin 27-22 or equivalent, or replaced prior to further flight.

(a) Cracked foreflaps may be operated for an additional 10 hours' time in service provided:

(1) The crack emanating from any one rivet hole does not extend more than 1/2 inch forward or 1 inch aft of the rivet hole.

(2) No two cracks are closer together (spanwise) than 4 inches.

(3) Each crack is stop drilled approximately 1/4-inch diameter.

(4) Each crack is visually inspected after each flight.

(b) Foreflaps operated under paragraph (a) shall be repaired in accordance with Convair Alert Service Bulletin A-27-22 or equivalent, modified per Convair Service Bulletin 27- 22 or replaced either at the end of this period of 10 hours' time in service or when a crack is found to progress beyond the stop drill hole, whichever occurs first. Repaired foreflaps may be operated for an additional 100 hours' time in service before modification or replacement provided that no further cracks are found during the daily inspections which exceed the limits specified in paragraph (a)(1) and (2). If such cracks are found, the foreflaps must be replaced or modified prior to further flight, except ferry flight in accordance with paragraph (c).

(c) Aircraft having cracks in the foreflaps which exceed the limits specified in paragraph (a)(1) and (2) may be flown under the provisions of CAR's 1.76 and 1.77 to a base where the required replacements or modifications are to be made.

(d) After the foreflaps are modified per Convair Service Bulletin 27-22 or equivalent, inspections may then be made at the normal inspection periods.

(Convair Service Bulletin 27-22 and Alert Service Bulletin A-27-22 cover this subject.)

This directive effective April 10, 1961.
