FAA Statement on Pratt & Whitney Engine Emergency Airworthiness Directive
The FAA issued an Emergency Airworthiness Directive (AD) tonight that requires U.S. operators of airplanes equipped with certain Pratt & Whitney PW4000 engines to inspect these engines before further flight.
The FAA is taking this action as the result of a fan-blade failure that occurred Saturday on a Boeing 777-200 that had just departed from Denver International Airport. Although the aircraft landed safely, the failure resulted in damage to the engine, an in-flight engine fire, and damage to the airplane.
After reviewing the available data and considering other safety factors, the FAA determined that operators must conduct a thermal acoustic image (TAI) inspection of the large titanium fan blades located at the front of each engine. TAI technology can detect cracks on the interior surfaces of the hollow fan blades, or in areas that cannot be seen during a visual inspection.
As these required inspections proceed, the FAA will review the results on a rolling basis. Based on the initial results as we receive them, as well as other data gained from the ongoing investigation, the FAA may revise this directive to set a new interval for this inspection or subsequent ones.
The previous inspection interval for this engine was 6,500 flight cycles. A flight cycle is defined as one takeoff and landing.
This AD is effective immediately upon receipt. The FAA will share this information with other international civil aviation authorities.
FAA Announces Application Period for LAANC [unmanned air systems]
The FAA announced the application period for entities to become FAA Approved UAS Service Suppliers of the Low Altitude Authorization and Notification Capability (LAANC). The application period opens on May 3, 2021.
LAANC is a collaboration between the FAA and the drone industry that directly supports the safe integration of drones into the nations airspace. Launched in 2017, the capability covers 80 percent of controlled National Airspace at 400 feet or below and expedites the time it takes for drone pilots to receive near real-time authorizations to fly in this space. All drone pilots operating in LAANC-enabled areas under the FAAs small drone rule or under the exception for limited recreational operations can access the capability through FAA Approved LAANC Service Suppliers.
LAANC provides drone pilots with industry developed applications to obtain near real-time airspace authorizations for operations in a controlled airspace below 400 feet. LAANC does not provide entities with the authority to regulate the airspace or grant access without FAA approval.
The Schedule is:
- Application Period: May 3 June 4, 2021
- FAA Submission Review: June 7 July 9, 2021
- Technical Interviews: June 12 August 13, 2021
- Formal Onboarding: August 16 October 15, 2021
The FAA is announcing the application date more than two months in advance to help applicants prepare, as they must have a mature product at time of application. Information on requirements and the onboarding process can be found on FAA.gov.
