We propose to adopt a new airworthiness directive (AD) for certain McDonnell Douglas Model 717-200 airplanes. This proposed AD would require inspecting the drive assembly of the aft elevator standby loop for interference between the clevis and bolt of the bellcrank assembly, correct orientation of the pull-pull cable clevis bolt, and excessive freeplay of the bellcrank assembly bearing, and corrective actions if necessary. This proposed AD would also require modifying the pull-pull cable clevis in the drive assembly of the aft elevator standby loop for certain airplanes. This proposed AD results from a report of an aborted takeoff due to a control column disconnect. We are proposing this AD to prevent binding of the bolt that connects the cable 264A clevis to the bellcrank assembly against the adjacent (upper) clevis of the pull-pull cable assembly. This binding condition could result in slow airplane rotation or a control column disconnect during takeoff and a runway excursion if takeoff must be aborted.

The FAA proposes to adopt a new airworthiness directive (AD) for certain Boeing Model 747 airplanes and Model 767 airplanes. This proposed AD would require revising the airplane flight manual to advise the flightcrew to use certain procedures during descent in certain icing conditions. This proposed AD results from reports of several in- flight engine flameouts, including multiple dual engine flameout events and one total power loss event, in ice-crystal icing conditions. We are proposing this AD to ensure that the flightcrew has the proper procedures to follow in certain icing conditions. These certain icing conditions could cause a multiple engine flameout during flight without the ability of the engines to be relit, and consequent forced landing of the airplane.

The FAA is adopting a new airworthiness directive (AD) for certain Hawker Beechcraft Corporation (HBC) Models B200, B200GT, B300, and B300C airplanes. This AD requires you to fabricate and install a placard incorporating information that limits operation when there is known or forecast icing and requires you to replace a section of the pneumatic supply tube for the tail deice system with a new tube of a different material. This AD results from reports of collapsed tail deice boot pneumatic supply tubes. We are issuing this AD to prevent collapsed pneumatic supply tubes, which could result in failure of the tail deice boots to operate. This failure could lead to loss of control in icing conditions.
