75-11-03 SEMCO BALLOONS: Amendment 39-2200. Applies to Model T, Model TC-4A and Model Challenger balloons certificated in the Balloon category.
Compliance required as indicated.
Improper owner/operator assembly of the deflation system has resulted in excessive force being required to operate the deflation cable and fraying of the deflation cable end. The frayed cable end may draw deflation sleeve material into the hole in the locking block and brass rod preventing proper operation of the deflation system. To prevent these occurrences, accomplish the following:
(a) Prior to each flight after the effective date of this AD, and until Revision 1, dated April 18, 1975, or later equivalent FAA approved revision to the Balloon Flight Manual is incorporated, accomplish the following check procedures. The pilot may perform these check procedures.
1. Check the portion of the end of the deflation cable which protrudes from the side of the aluminum locking block stamped "out" for fraying or loose strands with the hand or a cloth. If not smooth and free of loose strands, repair or replace before further flight.
2. During inflation, check the routing of the deflation cable. The deflation cable should lead from the basket through the fairlead ring sewn to the inside of the envelope, then in a straight line to the side of the locking block marked "in" and then to the outside of the envelope. The cable should not wrap around the locking block. If cable routing is not correct, reassemble the deflation system properly prior to flight.
(b) Within 20 hours time in service after the effective date of this AD, obtain and incorporate Revision 1, dated April 18, 1975, or later equivalent FAA approved revision in the applicable Balloon Flight Manual.
NOTE: Revision 1, dated April 18, 1975, to the applicable Balloon Flight Manual may be obtained on request to Semco Balloons, Route 3, Box 514, Griffin, Georgia 30223. The model of the balloonfor which the revision is desired should be specified, also the name and address to which it is desired that the revision be sent. These revisions are also available for examination in Room 274, FAA Building, 3400 Whipple Avenue, East Point, Georgia 30344.
This amendment becomes effective May 19, 1975.
