Action
Notice of proposed rulemaking (NPRM).
Summary
We propose to supersede Airworthiness Directive (AD) 2012-03- 04, for certain Airbus Model A310 series airplanes. AD 2012-03-04 currently requires, for certain airplanes, modifying the wire routing and installing additional protective sleeves. Since we issued AD 2012- 03-04, we received reports of new interferences of newly routed wire bundle 2S. This proposed AD would continue to require the actions in AD 2012-03-04, and would require additional work for certain airplanes. We are proposing this AD to prevent short circuits leading to arcing, and possible fuel tank explosion.
