Applicability*9

This AD applies to Empresa Brasileira de Aeronautica S.A. (EMBRAER) Model EMB-145, -145ER, -145MR, -145LR, -145MP, and -145EP airplanes; and Model EMB-135BJ, -135ER, -135KE, -135KL, and -135LR airplanes; certificated in any category; all serial numbers.

Compliance

You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.

Required actions

Within 5,000 flight hours or 48 months after the effective date of this AD, whichever occurs first: Install or rework, as applicable, metallic diverters and aluminum sheets; modify the light assembly on the tail boom rear movable fairing; and replace the hood assembly with a new hood assembly having part number (P/N) 145-23046-403 and reroute its electrical harness. Do all the actions in accordance with the Accomplishment Instructions of EMBRAER Service Bulletin 145LEG-55-0013, dated September 8, 2011 (for Model EMB-135BJ airplanes); or EMBRAER Service Bulletin 145-55-0030, Revision 05, dated July 29, 2011 (for Model EMB-145 and EMB-135, except -135BJ, airplanes).

Unsafe condition

This AD was prompted by a report of a lightning strike hitting an airplane tail boom causing certain rear bulkhead parts to jam an elevator control rod. We are issuing this AD to prevent lightning strikes from causing certain parts to contact the airplane pitch control system, which could reduce airplane controllability.

Affected ADs

None.
