The Federal Aviation Administration (FAA) are adopting a new airworthiness directive (AD) for certain The Boeing Company Model DC-10-10, DC-10-10F, DC-10-30, DC-10-30F (KC-10A and KDC-10), DC-10-40, MD-10-10F, and MD-10-30F airplanes. This AD was prompted by an evaluation by the design approval holder (DAH) indicating that the forward cargo compartment frames are subject to widespread fatigue damage (WFD). This AD requires an inspection of the attachment holes at the forward cargo compartment frames and the cargo liner for cracking, and repair if necessary. This AD would also require installing new oversized fasteners in the forward cargo compartment frames. We are issuing this AD to prevent fatigue cracking of the forward cargo compartment frames, which could result in loss of the fail-safe structural integrity of the airplane.
Prior to the accumulation of 30,000 total flight cycles, or within 72 months after the effective date of this AD, whichever occurs later: Do a high frequency eddy current inspection for cracking of the attachment holes at the forward cargo compartment frames and the cargo liner, in accordance with the Accomplishment Instructions of Boeing Service Bulletin DC10-53-182, dated June 28, 2013. If any crack is found, before further flight, repair using a method approved in accordance with the procedures specified in paragraph (i) of this AD.

BOEING HAS RESPONDED TO THIS RULE PROPOSAL, AND HAS AGREED:
In addition, the FAA also has announced a potential electrical issue with the AIRBUS Model Aircraft (not manufactured by Boeing):
The FAA is adopting a new airworthiness directive (AD) for certain Airbus Model A330-200 and -300 series airplanes, and Model A340-200 and -300 series airplanes. This AD was prompted by a report of contact between certain electrical harnesses and the hatrack rod that could cause chafing between the harnesses and surrounding structure. This AD requires modifying the routing of certain electrical harnesses. We are issuing this AD to prevent chafing and possible short circuit of two oxygen chemical generator containers in different wiring routes, which could result in malfunction of the electrical opening of all the containers connected to these routes. Such conditions, during a sudden depressurization event, could result in lack of oxygen and consequent injuries to airplane occupants.
ABOUT THE DC-10
Six commercial models of the DC-10 were developed. All versions of the trijet transport accommodate from 250 passengers, in a typical mixed first class and coach arrangement, to 380 in all-economy seating.
