Notice of Intent To Request Revision From the Office of Management and Budget of a Currently Approved Information Collection Activity, Request for Comments; Commercial Air Tour Limitations in the Grand Canyon National Park Special Flight Rules Area
The FAA invites public comments about our intention to request the Office of Management and Budget (OMB) to approve a current information collection, Certain organizations may apply to perform certification functions on behalf of the FAA. The FAA uses the information gathered from Grand Canyon National Park air tour operators to monitor their compliance with the Federal regulations.
Airworthiness Directives; Thielert Aircraft Engines GmbH (TAE) Model TAE 125-02-99 Reciprocating Engines
We are adopting a new airworthiness directive (AD) for the product listed above. This AD results from mandatory continuing airworthiness information (MCAI) issued by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as:
Airworthiness Directives; Rolls-Royce plc RB211-535E4-37, RB211-535E4-B-37, and RB211-535E4-B-75 Series Turbofan Engines
The FAA is superseding an existing airworthiness directive (AD) for Rolls-Royce plc (RR) RB211-535E4-37, RB211-535E4-B-37, and RB211-535E4-B-75 series turbofan engines. That AD currently requires initial and repetitive ultrasonic inspections of installed low pressure compressor (LPC) fan blade roots on-wing and during overhaul, and relubrication according to accumulated life cycles. Also, that AD introduces application of Metco 58 blade root coating as an optional terminating action. This AD requires the same actions but adds compliance paragraphs to relax the compliance schedule for repetitive inspections for fan blades operating within RB211-535E4 flight profiles A and B, if certain requirements are met. This AD also relaxes the initial compliance threshold by extending the cycles at which an initial inspection is required. This AD results from RR issuing Mandatory Service Bulletin (MSB) No. RB.211-72-C879, Revision 5 and Revision 6, that introduced a relaxed repetitive compliance schedule for fan blades operating within RB211-535E4 flight profiles A and B, if certain requirements are met, and introduced a relaxed initial compliance threshold. We are issuing this AD to detect cracks in LPC fan blade roots, which if not detected, could lead to uncontained multiple fan blade failure, and damage to the airplane.
Airworthiness Directives; Cessna Aircraft Company 150 Series Airplanes
We are adopting a new airworthiness directive (AD) for certain Cessna Aircraft Company (Cessna) 150 series airplanes with the BRS-150 Parachute System installed via Supplemental Type Certificate (STC) SA64CH. This AD requires you to replace the pick-up collar support and nylon screws for the BRS-150 Parachute System. This AD results from notification by Ballistic Recovery Systems, Inc. (BRS) that the pick-up collar assembly may prematurely move off the launch tube and adversely affect rocket trajectory during deployment. We are issuing this AD to prevent premature separation of the collar. This condition could result in the parachute failing to successfully deploy.
