The FAA released a safety alert for operators (Safo) last week for the Cessna Citation 500 reminding pilots to observe the Citation’s operating limitations by ensuring aileron trim is properly set before takeoff. The Safo also highlights the need to avoid excessive use of trim in flight. A Citation 500 operated under Part 135 rules crashed in 2007 shortly after takeoff, killing the two pilots and four passengers.

Last May, Aviation Partners issued Service Bulletin SBH-13-001 limiting winglet-equipped 800-series Hawkers to a maximum permissible altitude of 34,000 feet. The result of reported vibrations and aileron/wing oscillations, the SB prompted the FAA to issue an Airworthiness Directive calling for operators to comply with the service bulletin within 45 days.

For many years, a small company named Lam Aviation has showcased its variable-geometry wing design at EAA AirVenture. Company founder Lawrence Lam (who passed away in 2010) even designed and built his own low-wing, retractable gear, single-engine airplane–the Wanderer–to demonstrate the concept and flew that airplane to Oshkosh three times.

The FAA has approved a process to remove an altitude restriction on 800-series Hawkers equipped with winglets developed by Aviation Partners (API). The agency issued an airworthiness directive in June, requiring operators to comply with API service bulletin SBH-13-001, which limited maximum altitude to 34,000 feet until a fix could be developed. AD 2013-11-16 was “prompted by reports of several instances of severe vibration and wing/aileron oscillations,” according to the FAA.

In a Service Bulletin issued May 3, winglet manufacturer Aviation Partners (API) instructed operators with winglet-equipped 800-series Hawkers modified by STC#ST01411SE to reduce maximum permissible altitude to 34,000 feet. “Several instances of aileron/wing oscillations have been reported on the Hawker 800 [series],” the company said. “Aviation Partners and the FAA consider this Service Bulletin to be a safety-related limitation until a design change to preclude the oscillations is developed and FAA approved.”

The FAA has issued a notice of proposed rulemaking for an Airworthiness Directive for certain Embraer Phenom 300s. It is based on an unsafe condition as a result of an inadequate number of drain holes in the primary control surfaces (rudder, elevators and ailerons), which may allow water to accumulate in the control surfaces.

The FAA has issued an Airworthiness Directive for the Gulfstream Aerospace Galaxy and Gulfstream 200, citing cracked nuts found on the aircraft’s production line during routine post-assembly inspection. Investigation revealed that the cracks resulted from hydrogen embrittlement combined with high hardness.
