July 24,2013


Aviation Rulemaking Advisory Committee (ARAC) Airman Testing Standards and
Training Working Group (ATSTWG) [FR DOC# 2013-17782] SUMMARY: This notice
announces the availability of additional draft Airman Certification
Standards (ACS) documents developed by the ATSTWG for the authorized
instructor certificate, the private pilot certificate and the instrument
rating. These documents are available for public review, download, and

Airworthiness Directives; BAE Systems (Operations) Limited Airplanes [FR
DOC# 2013-17764] SUMMARY: We propose to supersede an existing airworthiness
directive (AD) that applies to all BAE Systems (Operations) Limited Model
BAe 146 series airplanes and Model Avro 146-RJ series airplanes. The
existing AD currently requires revising the maintenance program by
incorporating certain airworthiness limitations that require new life limits
on certain main landing gear (MLG) components. Since we issued that AD, we
have determined that reduced safe life limits on certain nose landing gear
(NLG) fittings are necessary. Analysis of these fittings showed the presence
of forging indications in the flash line, which might reduce the life limits
of these fittings.

Airworthiness Directives; Dassault Aviation Airplanes [FR DOC# 2013-17765]
SUMMARY: We propose to adopt a new airworthiness directive (AD) for all
DASSAULT AVIATION Model FAN JET FALCON; Model MYSTERE-FALCON 200 airplanes; and Model MYSTERE-FALCON 20-C5, 20-D5, 20-E5, and 20-F5 airplanes. This proposed AD was prompted by reports of defective fire extinguisher bottle
cartridges. This proposed AD would require checking manufacturing references
of pyrotechnical cartridges for batch number and date, repetitive checking
of cartridges for electrical continuity, and replacing defective
pyrotechnical cartridges if necessary. We are proposing this AD to detect
and correct defective fire bottle cartridges, which could affect the
capability to extinguish a fire in an engine, auxiliary power unit, or rear
compartment, which could result in damage to the airplane and injury to the

Airworthiness Directives; Eurocopter France (Eurocopter) Helicopters [FR
DOC# 2013-17622] SUMMARY: We are adopting a new airworthiness directive (AD)
for Eurocopter Model AS350B, AS350BA, AS350B1, AS350B2, AS350B3, AS350C,
AS350D, and AS350D1 helicopters with a single hydraulic system and a certain
hydraulic pump drive installed. This AD requires inspecting the hydraulic
pump drive pulley bearing (pulley bearing) for leaks, rust, overheating, and
condition. This AD is prompted by six reports of hydraulic pump drive belt
failure caused by seizure of the pulley bearing. These actions are intended
to prevent hydraulic pump drive belt failure, loss of hydraulic servo
assistance, and subsequent loss of control of the helicopter.
