Models named: EMB-135ER, -135KE, -135KL, -135LR, -145, -145ER, -145MR, -145LR, -145XR, -145MP. Read the applicability below — it usually turns on serial or part numbers too.

Applicability*9

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

Compliance

Comply with this AD within the compliance times specified, unless already done.

Required actions

Within 5,000 flight hours or 24 months after the effective date of this AD, whichever occurs first: Check the airplane maintenance records to determine whether the actions specified in Embraer Service Bulletin 145-27-0115 have been done. If the records review is inconclusive, inspect the engine control box assembly against the Accomplishment Instructions of Embraer Service Bulletin 145-27-0115, Revision 03, dated October 5, 2015, to determine whether the actions specified in Embraer Service Bulletin 145-27-0115 have been done.

Unsafe condition

This AD was prompted by a report of airplanes with modified gust lock levers that performed take-offs or rejected take-offs (RTOs), in such a configuration that the gust lock lever prevented the thrust lever's full excursion, thus limiting the engine power to about 70% of the nominal take-off power. We are issuing this AD to prevent incorrect configuration of the gust lock lever, which could reduce the airplane's performance during take-offs or attempted take-offs, increase the required take-off distance or the RTO distance, and reduce the airplane's capacity to clear obstacles.

Affected ADs

None.
