## Abstract

We are adopting a new airworthiness directive (AD) for certain Bombardier, Inc., Model DHC-8-102, -103, and -106 airplanes; Model DHC- 8-200 series airplanes; and Model DHC-8-300 series airplanes. This AD was prompted by a report that a certain modification to the auto relight system is incompatible with a certain beta lockout system modification and could result in de-activation of the auto ignition feature of the No. 2 engine. This AD requires an inspection of the auto ignition system and applicable rectification. We are issuing this AD to address the unsafe condition on these products.
