FAA Propose Phenom Airworthiness Directive

The FAA has issued a notice of proposed rulemaking for an Airworthiness Directive for certain Embraer Phenom 300s. It is based on an unsafe condition as a result of an inadequate number of drain holes in the primary control surfaces (rudder, elevators and ailerons), which may allow water to accumulate in the control surfaces. According to the FAA, the condition could cause unbalanced flight control surfaces and reduced flutter margins, which could result in loss of control of the airplane. The FAA is taking comments until June 8.
