Department of Transportation January 18, 2005 – Federal Register Recent Federal Regulation Documents

The FAA proposes to adopt a new airworthiness directive (AD) for all Boeing Model 747-200C and 747-200F series airplanes. This proposed AD would require repetitive inspections for cracking of the left and right C-3 frame upper closure fittings of the nose cargo door, and corrective actions if necessary. This proposed AD also provides an optional modification that, if done, would terminate inspections in certain areas. This proposed AD is prompted by reports indicating that fatigue cracking was found in the inboard flange above the flight deck floor on the C-3 frame upper closure fittings of the nose cargo door. We are proposing this AD to detect and correct cracking of the C-3 frame upper closure fittings, which could extend and result in rapid depressurization of the airplane.

This document announces a public meeting of interest to owners and operators of Raytheon Aircraft Company (Raytheon) Beech Models 45 (YT-34), A45 (T-34A, B-45), and D45 (T-34B) airplanes. The purpose of the meeting is to discuss technical issues and potential corrective actions related to the continued operational safety of the affected airplanes, specifically related to the structural fatigue of critical structure and Airworthiness Directive (AD) 2004-25-51.
