Full official abstract

We are adopting a new airworthiness directive (AD) for certain Quest Aircraft Design, LLC (Quest) Model Kodiak 100 airplanes. This AD requires you to inspect the torque of the inertial particle separator (IPS) bolts; correct the torque, if necessary; replace the IPS bolts with new IPS bolts within a certain time; and install safety wire around the new IPS bolts. This AD was prompted by five instances where a loose IPS bolt was found on the right-hand side of the engine bypass door attachment. This condition, if not corrected, could lead to an inoperable bypass door, which could result in engine inlet icing with consequent loss of engine power and forced landing. We are issuing this AD to correct the unsafe condition on these products.
