BOEING ORDERED TO CHECK DC-10 AIRCRAFT FOR POTENTIAL CRACKS IN AIRFRAME AFFECTING SAFETY OF FLIGHT

October 28th, 2014
Washington, DC

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.

For service information identified in this AD, contact Boeing Commercial Airplanes, Attention: Data & Services Management, 3855 Lakewood Boulevard, MC D800-0019, Long Beach, CA 90846-0001; telephone 206-544-5000, extension 2; fax 206-766-5683

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.

  • The Series 10 model was designed for service on routes of up to 4,000 statute miles (6,436 km) and is powered by General Electric CF6-6 engines, each rated at 40,000 pounds (17,144 kg) takeoff thrust. The first flight was made on Aug. 29, 1970. Federal Aviation Administration (FAA) certification was received for airline service on July 29, 1971. First deliveries were made jointly to American Airlines and to United Airlines. Scheduled commercial flights began Aug. 5, 1971.
  • The intercontinental range Series 40, powered by Pratt & Whitney JT9D turbofan engines, with nonstop range up to approximately 5,800 miles (9,322 km), was introduced to service in 1972.
  • The Series 30, an intercontinental model with a range of approximately 5,900 miles (9,493 km), also introduced in 1972, is equipped with General Electric CF6-50 fanjets.
  • The DC-10 Convertible Freighter, first delivered in 1973, can be arranged to carry all passengers or all cargo and is available in the basic Series 10, Series 30 or Series 40. All versions have available cargo space of more than 16,000 cubic feet (453 cu m), as much capacity as four 40-foot (12.19-m) railroad freight cars, or up to 380 passengers.
  • The Series 15, launched in 1979, combines the basic smaller airframe of the Series 10 with a version of the more powerful engines used on the longer-range Series 30s. The combination gives the Series 15 outstanding performance with full loads from high-altitude airports in hot climates.
  • The DC-10 Series 30F, an all-freighter model, was ordered by Federal Express in May 1984. First delivery was made Jan. 24, 1986. This pure freighter version will carry palletized payloads of up to 175,000 pounds (79,380 kg) more than 3,800 miles (6,115 km).
