Airworthiness Directive · Amendment 39-14480 · Hamburger Flugzeugbau GmbH Model HFB 320 HANSA Airplanes
Hamburger Flugzeugbau GmbH Model HFB 320 HANSA Airplanes
This AD applies to all Hamburger Flugzeugbau GmbH Model HFB 320 HANSA airplanes, certificated in any category.
The FAA is adopting a new airworthiness directive (AD) for all Hamburger Flugzeugbau GmbH Model HFB 320 HANSA airplanes. This AD requires revising the Limitations section of the HFB 320 Hansa Airplane Flight Manual to prohibit operation of the airplane past its designed life limit for the primary structure, which is 15,000 flight hours or 15,000 fight cycles, whichever occurs first; and to require contacting the FAA for approval of analysis that the airplane is safe to continue operation beyond the designed life limit. This AD results from a report that all airplanes in operation might have met or exceeded the designed life limit for the primary structure. We are issuing this AD to prevent continued operation of an airplane beyond its designed life limit for the primary structure, which could result in reduced structural integrity of the airplane.
You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.
Within 30 days after the effective date of this AD: Revise the Limitations section of the HFB 320 Hansa Airplane Flight Manual (AFM) to state the following (or insert a copy of this AD into the Limitations section):
“Do not operate the airplane beyond 15,000 total flight cycles, or 15,000 total flight hours, whichever occurs first.”
(g) This limitation may be removed from the HFB 320 Hansa AFM after the Manager, International Branch, ANM-116, FAA, approves analysis that would substantiate continued safe operation beyond the designed life limit of 15,000 total flight cycles, or within 15,000 total flight hours on the airplane, whichever occurs first.
