## Summary

We propose to adopt a new airworthiness directive (AD) for all Airbus Model A300 series airplanes; Airbus Model A300 B4-600, B4-600R, and F4-600R series airplanes, and Model A300 C4-605R Variant F airplanes (collectively called Model A300-600 series airplanes); and A310 series airplanes. This proposed AD was prompted by reports of failures of the right inner tank fuel pump. This proposed AD would require repetitive functional tests of the circuit breakers for the fuel pump power supply, and replacement of any circuit breaker that fails any functional test or is found to be stuck closed. We are proposing this AD to detect and correct failure of the thermal fuses in the fuel pumps, which could result in a fuel pump overheating, leading to a fuel tank explosion.
