The FAA has issued an NPRM to supersede airworthiness directive 2013-21-01, which currently applies to the Airbus Helicopters AS350B/BA/B1/B2/B3/C/D/D1 and AS355E/F/F1/F2/N/NP. The current AD requires certain inspections of each tail-rotor pitch horn assembly for a crack and, if there is a crack, replacing the pitch horn with an airworthy pitch horn before further flight. It also requires a one-time visual inspection for pitch horns above certain hours time-in-service (TIS).
A proposed Learjet 45 FAA airworthiness directive is prompted by reports of non-conforming windshield supports (coupe rails). It would require a general visual inspection to detect gouging and scratches and to determine if a radius has been removed; an ultrasound inspection to measure the dimensions of the lower coupe rails; an eddy current inspection to detect cracks of the lower coupe rails; replacement of the lower coupe rails if necessary; and revision of the maintenance or inspection program, as applicable.
Constant Aviation completed its seventeenth 96-month inspection on the Legacy 600. The MRO has been a Legacy authorized service center since 2002. “The work is performed at our Cleveland facility and takes about 35 days,” CEO Steve Maiden told AIN. The company has performed more than fifty-five 48-month and more than twenty 72-month inspections. “We were the first authorized service center to complete a 48-month and 96-month inspection,” Maiden said.
Air Services, a division of Constant Aviation providing off-wing aircraft support headquartered at Cleveland Hopkins International Airport, has completed the requirements of the Cessna Citation NDI certification program and has been named an authorized independent NDI facility. The designation allows the company to perform NDT inspections and testing on all Cessna Citations.
The FAA is adopting a new Airworthiness Directive that supersedes an existing airworthiness directive for the MD Helicopters MD900. It requires a visual inspection and, if necessary, an eddy-current inspection of the main rotor lower hub assembly (lower hub) for a crack. If a crack exists, the AD requires replacing the lower hub with an airworthy lower hub before further flight.
Jet Aviation recently added three customized service vehicles, bringing the total number available in the U.S. to five. The other two are located at Teterboro and Boston/Bedford. “Our mobile maintenance service vehicles provide the same quality of service that our customers get when they are in our service centers; it’s simply packaged ‘to go,” said Chuck Krugh, senior vice president of Jet Aviation St. Louis.
In another safety issue affecting the Sikorsky S-92 helicopter’s main gearbox, on July 18 the FAA released an airworthiness directive (AD) that calls for inspection for cracks. The AD was prompted by the discovery of a crack in the gearbox housing of one S-92, “in the cored passage area adjacent to the scissor bracket mount,” allowing oil to leak. The result could be a loss of oil and subsequent failure of the gearbox, the FAA said.
The EASA and FAA have issued new emergency Airworthiness Directives (ADs) for the Eurocopter EC135 after detection of cracks on the lower hub-shaft flange of two more of the light twins. The ADs require repetitive preflight inspections.

Hawker Beechcraft has increased the Premier I/IA inspection time from a 200-hour core interval to a 600-hour interval. The extended inspection period applies to all new and in-service Premier I/IAs. The new schedule requires an “A” inspection every 600 hours and an “A and B” inspection every 1,200 hours. The company has reformatted Chapter 12 for the aircraft to align with the change and removed all previous inspection guides.
