other aircraft types with pitot issues

FR Doc E8-20702
cracks:
Docket No. FAA-2009-0005; Directorate Identifier 2008-NM-164-AD]
"This proposal would require operators to inspect the pitot tubes. If cracks are found in the tubes, they would need to be replaced, per the instructions of CASA Service Bulletin SB-212-34-11, Rev. 1 (dated Feb. 27, 2008).
This proposed AD, which resulted from an MCAI originated by the European Aviation Safety Agency, was prompted by the discovery of cracked pitot tubes on Britten-Norman BN-2 aircraft, which use the same Thales Optronics pitot tubes as are found on CASA C-212s.
Cracked pitot tubes could result in incorrect readings on the pressure instrumentation (e.g., altimeters, vertical speed indicators and airspeed indicators), potentially leading to navigational errors. FAA estimates that this proposed AD would affect 32 aircraft on the U.S. Registry and cost U.S. operators a total of $2,560, or $80 per airplane. Comments on this proposal, which are due March 25, should be sent to the DOT Docket Web site:"

United Airlines aircraft aborts flight due to faulty airspeed indicator
A United Airlines aircraft flying from Los Angeles to Washington DC was forced to abort its flight after was smoke was detected in the cockpit.
The aircraft - an Airbus A320, carrying 122 passengers - had been in flight for about 40 minutes when smoke began entering the cockpit. The flight returned to Los Angeles International Airport, where the passengers safely disembarked from the aircraft.
According to officials, the smoke occurred after a Pitot tube (which indicates airspeed) mounted on the fuselage overheated. The aircraft was expected to return to service once the faulty part was replaced, reported Reuters."
