To prevent inadvertent deflation panel opening in flight, accomplish the following:

(a) Prior to the next inflation, and during each subsequent preflight inspection, after the effective date of this AD:

(1) Check the synthetic fastener tape, known as hook and pile (Velcro), of the deflation panel system for broken hook and pile, or deterioration caused by heat, in accordance with paragraph A of General Balloon Corporation Service Letter Number 7, dated March 17, 1981, (hereafter referred to as General Balloon Letter No. 7).

(2) Repair all areas of hook and pile found to be unserviceable during check (a)(1), in accordance with paragraph G of General Balloon Letter No. 7.

(3) After accomplishment of (a)(1) and (a)(2), conduct a side shear load transfer capability check of the hook and pile, in accordance with paragraph B of General Balloon Letter No. 7. If hook and pile separate, accomplish either (i) or (ii) as follows:

(i) Have the side shear load transfer capability of the hook and pile retested by a rated mechanic or certified repair station, in accordance with paragraph E of General Balloon Letter No. 7, and replace all areas of hook and pile unable to sustain the side shear load with like serviceable fastener tape.

(ii) Have a rated mechanic or certified repair station replace areas of hook and pile that did not pass the side shear load transfer capability check conducted in paragraph (a)(3) with like serviceable fastener tape.

(4) Preflight checks conducted in accordance with Piccard Balloon Ax-6 Balloon Flight Manual (BFM) Revision No. 9, dated April 2, 1981, deletes the requirements for subsequent preflight checks specified in paragraph (a) of this AD.

(b) Prior to next inflation, after the effective date of this AD, install an approved mechanical latch (i.e., a Capewell) at the apex of the balloon envelope, in accordance with the balloon manufacturer's instructions as approved by the FAA.

(c) At intervals not to exceed 100 hours time in service or at each annual inspection after the effective date of this AD, whichever comes first, accomplish side shear load transfer capability test of the hook and pile fastener tape, in accordance with paragraph E of General Balloon Letter No. 7. Replace areas of degraded hook and pile fastener tape with like serviceable fastener tape.

The manufacturer's specifications and procedures identified and described in this directive are incorporated herein and made a part hereof pursuant to 5 U.S.C. 553(a)(1). All persons affected by this directive who have not already received these documents from the manufacturer may obtain copies upon request to General Balloon Corporation, P.O.
