Summary

The FAA is withdrawing a previously published Notice of Proposed Rulemaking (NPRM) (54 FR 38610, September 19, 1989) that would provide improved engine cowling retention for transport category airplanes by adding specific design requirements for cowling retention systems. The proposed rule would have promoted design and construction of cowling retention systems to withstand vibration, inertial loads, over-pressure, normal air loads, and thermal conditions of an engine compartment fire after failure or improper fastening of latching devices. We are withdrawing the proposed rule because the proposal has been surpassed by technological advances. The issues will be addressed by future regulatory action based on recommendations from the Aviation Rulemaking Advisory Committee, and will be harmonized with similar regulations in Europe and Transport Canada.
