Airworthiness Directive · Amendment 39-22089 · Fuel storage
Cameron Balloons Ltd. Fuel Cylinders
Superseded. A later AD replaced this one: AD 2023-17-09. Comply with the one in force.
(1) This AD applies to hot air balloons, certificated in any category, equipped with a Cameron Balloons Ltd. part number (P/N) CB2990 (Alugas) fuel cylinder (the affected fuel cylinder).
(2) The affected fuel cylinder may be installed on hot air balloon models including, but not limited to, those of the following design approval holders:
(i) Aerostar International, Inc.;
(ii) Ballonbau Worner GmbH;
(iii) Balóny Kubíček spol. s.r.o.;
(iv) Cameron Balloons Ltd.;
(v) Eagle Balloons Corp.;
(vi) JR Aerosports, Ltd. (type certificate previously held by Sundance Balloons (US));
(vii) Lindstrand Balloons Ltd.; and
(viii) Michael D. McGrath (type certificate subsequently transferred to Andrew Philip Richardson, Adams Aerostats LLC).
The FAA is adopting a new airworthiness directive (AD) for certain Cameron Balloons Ltd. (Cameron) fuel cylinders installed on hot air balloons. This AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI identifies the unsafe condition as cracks in the weld between the cylinder valve plate and the upper dished end of Cameron part number (P/N) CB2990 (Alugas) fuel cylinders, which could allow uncontrolled fuel leakage of liquid propane. This AD requires the removal of any installed P/N CB2990 (Alugas) fuel cylinder from service before further flight. The FAA is issuing this AD to address the unsafe condition on these products.
Before further flight after the effective date of this AD, remove the affected fuel cylinder from service.
Note 1 to paragraph (g): Cameron Balloons Alert Service Bulletin No. 33, Revision 0, dated May 4, 2022, provides procedures for doing a leak check and emptying fuel from the Cameron P/N CB2990 (Alugas) fuel cylinder to render it safe for storage following the removal from service. These actions are not required by this AD.
