Airworthiness Directives; McDonnell Douglas Corporation Airplanes
Transportation Department, Federal Aviation Administration
What is this?
This is a regulatory record from Transportation Department, Federal Aviation Administration — a rule, proposed rule, or notice. Regulations carry the force of law once final, and often invite public comment before that point.
Why does it matter?
Regulations are usually what actually binds you, more than statutes are. This is where an agency states the requirement, the effective date, and whether there is still a window to respond.

Description
We are adopting a new airworthiness directive (AD) for certain Model DC-10-10, DC-10-10F, and MD-10-10F airplanes. This AD was prompted by reports of three instances of fuel leaks in the lower cap splice of the wing rear spar at station Xors=409. Investigation revealed the fuel leak was due to a crack in the lower cap. If not corrected, this condition could result in fuel leaks or cracking of the lower wing skin and structure, causing possible inability of the structure to sustain the limit load and adversely affecting the structural integrity of the airplane. This AD requires repetitive inspections for cracking on the lower cap of the rear spar of the left and right wings between stations Xors=417 and the outboard edge of the lower cap splice of the wing rear spar at station Xors=400; temporary and permanent repairs if necessary; and repetitive inspections of repaired areas, and corrective actions if necessary. We are issuing this AD to correct the unsafe condition on these products.
