| AD/B737/86 Amdt 1 | Body Station 344 to 360 Support Structure | 2/2005 |
|---|
| Applicability: | Model 737-100, -200, -300, -400, and -500 series aircraft; equipped with intercostal support structures at stringer 5R and having a number 2 galley weight of 996 pounds or more (including any attached equipment that imposes loads on the galley). |
|---|---|
| Requirement: | Action in accordance with the technical requirements of FAA AD 2004-23-07 Amdt 39-13862.Note: Boeing Special Attention Service Bulletin 737-53-1154 Revision 1, or later FAA approved revision, refer. |
| Compliance: | As specified in the Requirement document, with a revised effective date of 17 February 2005. |
| This Amendment becomes effective on 17 February 2005. | |
| Background: | This Directive was prompted by results of engineering tests and analyses, which revealed that certain fuselage support structure for the number 2 galley is unable to support certain loads that may occur during emergency landing conditions. If the fuselage structure breaks, the galley may shift and cause blockage of the forward service door.Amendment 1 is issued in response to a new FAA AD, which requires modification of the same support structure as required by the original issue of this Directive, but using new methods based on new calculations; and expands applicability to include additional aircraft. |
