Federal Aviation Administration April 21, 2014 – Federal Register Recent Federal Regulation Documents

The FAA is delaying the effective date of the Helicopter Air Ambulance, Commercial Helicopter, and Part 91 Helicopter Operations final rule published on February 21, 2014. In that rule, the FAA amended its regulations to revise the helicopter air ambulance, commercial helicopter, and general aviation helicopter operating requirements. The April 22, 2014 effective date does not provide an adequate amount of time for the affected certificate holders to implement the new requirements. By extending the effective date to April 22, 2015, the affected certificate holders will have sufficient time to implement the new requirements. This action will only affect the effective date of the provisions of the rule scheduled to take effect April 22, 2014. Other provisions in the rule with specified compliance dates will not be affected.

We propose to adopt a new airworthiness directive (AD) for certain Bombardier, Inc. Model CL-600-2B16 (CL-604 Variant) airplanes. This proposed AD was prompted by reports of in-flight uncommanded rudder movements. This proposed AD would require revising the airplane flight manual (AFM) to incorporate an uncommanded yaw motion procedure. We are proposing this AD to prevent in-flight uncommanded rudder movements, which could lead to structural failure and subsequent loss of the airplane.
