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.
