Hartzell Propeller has received an FAA type certificate for its new advanced-composite ASC-II four-blade propeller. It is the company’s first
ASC-II propeller developed for ­turboprop aircraft.

Hartzell developed its first composite blade in 1978 principally out of aramid fiber. According to the company, it was the first composite propeller ever certified by the FAA.

A Special Airworthiness Information Bulletin (SAIB NE-09-48) has been issued regarding propellers, or propeller component parts, repaired, inspected or overhauled by Western Aircraft Propeller Service of Troutdale, Ore. It is based on field service difficulty reports concerning two Hartzell propellers installed on a Hawker Beechcraft Baron E55.

Mitsubishi MU-2B-40, The Woodlands, Texas, May 1, 2001–The NTSB determined that the probable cause was the pilot’s failure to maintain airplane control following a loss of right engine power, which resulted in hitting terrain in an uncontrolled descent. A contributing factor was the loss of right engine power as a result of the fatigue failure of the propeller shaft coupling.

As an outgrowth of its continuing investigation into the November 12 crash of American Airlines Flight 587 in New York City, the NTSB has recommended that the FAA order manufacturers and operators of transport-category airplanes to revamp pilot-training programs with regard to rudder use.

Hawker Beechcraft King Air C90A, Emporia, Kan., Sept. 22, 2007–Following a severe high-frequency vibration in flight and an emergency landing, the King Air pilot found the right elevator trim tab push rod was broken. The NTSB blamed the incident on the improper installation of the trim tab attachment hardware by maintenance personnel, which resulted in excessive wear, fatigue and failure of the push-pull tube.

Boeing completed a redesign of a 737 rudder control system and, as expected, the FAA formally proposed an AD that will require the installation of the system on some 2,000 Boeing 737-100s, -200s, -300s and -400s within a five-year period.

Hartzell has introduced a four-bladed aluminum propeller conversion for the Fairchild Metro II that the company said reduces sound levels by 10 to 12 dBA, providing a quieter cabin and lower external noise. The diameter of the new prop system is reduced by five inches from that of the original three-blade system. An “advanced airfoil configuration” was also applied to the new blades, said Hartzell.

An AD issued last month requires the installation of a new rudder-control system on all U.S.-registered Boeing 737s before Nov. 12, 2008. An October 8 directive (AD 2002-20-07) stems from the investigation into two fatal accidents and a reported rudder event attributed, in part, to an uncommanded rudder hardover, rudder reversal or jammed rudder. Parts are expected to cost Boeing about $140,000 per aircraft.

Water that pooled under the floor panels of a Falcon 20, froze and restricted the movement of the aileron trim actuator as the airplane was landing at London Stansted Airport is to blame for the airplane’s “frozen” controls, according to the UK Air Accidents Investigation Branch.
