PO 00000 Frm 00001 Fmt 4702 Sfmt 4702 Background Why is FAA conducting this meeting? On December 7, 2004, the left wing of a Raytheon Beech Model A45 (T–34A), serial number G–13, separated from the airplane in flight. The airplane, operated by Texas Air Aces, crashed near Montgomery, Texas. The wing was found about a quarter mile away from the crash site. The left wing center section failed 4 inches inboard of the forward wing attach fitting. FAA investigation revealed visual evidence of fatigue not previously addressed by Airworthiness Directive (AD) 2001–13–18 and AD 2001–13–18 R1, which FAA issued as a result of a 2003 accident near Conroe, Texas. In November 2003, a Raytheon Beech Model A45 (T34A) airplane crashed after the right wing failed at Wing Station (WS) 34 on the forward spar and WS 66.00 on the rear spar. The airplane, operated by Texas Air Aces, crashed near Conroe, Texas. The wing was found about a quarter mile away from the crash site. On May 28, 1999, FAA issued priority letter AD 99–12–02 to address the inflight separation of the right wing on a Model A45 (T–34A) airplane. The airplane, operated by Sky Warriors, crashed near Rydall, Georgia, where the wing was found about a quarter mile away from the crash site. The left wing remained attached to the airplane following separation of the right wing. Examination of the right wing revealed structural fatigue cracks at several of the fracture surfaces. Although it did not separate from the airplane, the left wing showed several fatigue cracks at several locations. AD 99–12–02 required operating and speed restrictions on the affected airplanes and was superseded by AD 2001–13–18. Based on all data on these accidents including the additional visual evidence of fatigue not previously addressed by AD 2001–13–18 or AD 2001–13–18 R1, FAA issued emergency AD 2004–25–51. This emergency AD required an inspection and/or modification program approved specifically for this AD by FAA Wichita Aircraft Certification Office (ACO). In essence, AD 2004–25– 51 grounded the T–34 fleet because of evidence of fatigue in locations not evaluated from the first two accidents. The FAA took this action until the situation could be more fully E:\FR\FM\18JAP1.SGM 18JAP1 2826 Federal Register / Vol. 70, No. 11 / Tuesday, January 18, 2005 / Proposed Rules understood and proper actions taken to ensure the continued airworthiness of the fleet. All the technical aspects of this aging airplane issue need to be studied and understood in order for FAA to return the fleet to an airworthy status. The FAA will review and communicate (at the meeting) the events leading to emergency AD 2004–25–51 and the reasons for our action. The FAA will also provide its expectations for any actions the public may propose to restore the fleet to an airworthy and safe condition. The meeting will allow the public the opportunity to discuss technical issues and communicate potential corrective actions related to the continued operational safety of the affected airplanes, specifically related to the structural fatigue of critical structure and AD 2004–25–51. Public Meeting Procedures What procedures should I follow for this public meeting? If you plan to attend the public meeting, please be aware of the following: • There is no admission fee or other charge to attend or participate in this meeting. You are responsible for your own transportation and accommodations for the meeting. The meeting is open to all who requested in advance to present or who register on the day of the meeting. This is subject to availability of space in the meeting room. • FAA representatives will conduct the meeting. We will have a panel of technical experts and managers to discuss information on the subject. • The public meeting is intended as a forum to seek additional data and supporting methodologies from industry, the general public, and operators.

ACTION: Notice of proposed rulemaking (NPRM). AGENCY: SUMMARY: 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. PO 00000 Frm 00002 Fmt 4702 Sfmt 4702 We must receive comments on this proposed AD by March 4, 2005.

Background

    Why is FAA conducting this meeting? On December 7, 2004, the left 
wing of a Raytheon Beech Model A45 (T-34A), serial number G-13, 
separated from the airplane in flight. The airplane, operated by Texas 
Air Aces, crashed near Montgomery, Texas. The wing was found about a 
quarter mile away from the crash site.
    The left wing center section failed 4 inches inboard of the forward 
wing attach fitting. FAA investigation revealed visual evidence of 
fatigue not previously addressed by Airworthiness Directive (AD) 2001-
13-18 and AD 2001-13-18 R1, which FAA issued as a result of a 2003 
accident near Conroe, Texas.
    In November 2003, a Raytheon Beech Model A45 (T34A) airplane 
crashed after the right wing failed at Wing Station (WS) 34 on the 
forward spar and WS 66.00 on the rear spar. The airplane, operated by 
Texas Air Aces, crashed near Conroe, Texas. The wing was found about a 
quarter mile away from the crash site.
    On May 28, 1999, FAA issued priority letter AD 99-12-02 to address 
the in-flight separation of the right wing on a Model A45 (T-34A) 
airplane. The airplane, operated by Sky Warriors, crashed near Rydall, 
Georgia, where the wing was found about a quarter mile away from the 
crash site. The left wing remained attached to the airplane following 
separation of the right wing. Examination of the right wing revealed 
structural fatigue cracks at several of the fracture surfaces. Although 
it did not separate from the airplane, the left wing showed several 
fatigue cracks at several locations. AD 99-12-02 required operating and 
speed restrictions on the affected airplanes and was superseded by AD 
2001-13-18.
    Based on all data on these accidents including the additional 
visual evidence of fatigue not previously addressed by AD 2001-13-18 or 
AD 2001-13-18 R1, FAA issued emergency AD 2004-25-51. This emergency AD 
required an inspection and/or modification program approved 
specifically for this AD by FAA Wichita Aircraft Certification Office 
(ACO). In essence, AD 2004-25-51 grounded the T-34 fleet because of 
evidence of fatigue in locations not evaluated from the first two 
accidents. The FAA took this action until the situation could be more 
fully

understood and proper actions taken to ensure the continued 
airworthiness of the fleet.
    All the technical aspects of this aging airplane issue need to be 
studied and understood in order for FAA to return the fleet to an 
airworthy status. The FAA will review and communicate (at the meeting) 
the events leading to emergency AD 2004-25-51 and the reasons for our 
action. The FAA will also provide its expectations for any actions the 
public may propose to restore the fleet to an airworthy and safe 
condition.
    The meeting will allow the public the opportunity to discuss 
technical issues and communicate potential corrective actions related 
to the continued operational safety of the affected airplanes, 
specifically related to the structural fatigue of critical structure 
and AD 2004-25-51.
