Airworthiness Directives; The Boeing Company 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 propose to adopt a new airworthiness directive (AD) for certain The Boeing Company Model DC-9-10, DC-9-20, DC-9-30, DC-9-40, and DC-9-50 series airplanes; and Model DC-9-81 (MD-81), DC-9-82 (MD- 82), DC-9-83 (MD-83), DC-9-87 (MD-87), MD-88, and MD-90-30 airplanes, that are equipped with auxiliary fuel tanks. This proposed AD was prompted by fuel system reviews conducted by the manufacturer. This proposed AD would require adding design features to detect electrical faults, to detect a pump running in an empty fuel tank, and to ensure that a fuel pump's operation is not affected by certain conditions. We are proposing this AD to reduce the potential of ignition sources inside fuel tanks, which, in combination with flammable fuel vapors, could result in fuel tank explosions and consequent loss of the airplane.
