GARMIN G1000 PROBLEM AFFECTS GA DELIVERIES
(http://www.avweb.com/eletter/archive...ll.html#195931)
A problem with a component of the Garmin G1000 glass panel, a popular
choice for avionics in many general aviation aircraft, has stalled
production and delayed deliveries at factories around the country as
Garmin searches for a fix. The problem stems from a sudden increase in
failure rates in recent flight tests of new GRS 77 AHRS (Attitude
Heading Reference System) units used in G1000 installations, Garmin
said on Tuesday. A component failure in the GRS 77 results in a loss
of attitude information on the primary flight display. "After
communication with Garmin's OEM partners and the FAA, it was
determined that in all G1000 installations, continued safe flight can
be conducted with the stand-by attitude indicator and other available
instruments," the company said in a statement. "If pilots should
experience a failure of the GRS 77 AHRS, they should follow standard
procedures and refer to the standby attitude indicator."

COLUMBIA LAYS OFF 300, CITES GARMIN G1000 ISSUE
(http://www.avweb.com/eletter/archive...ll.html#195932)
At Columbia Aircraft in Bend, Ore., the company announced on Monday ()
that it would halt its production line and lay off about 300 workers
until problems with Garmin G1000s could be resolved. Although Garmin
says the AHRS problem does not require limitations on use of the
aircraft, Columbia spokesman Randy Bolinger told AVweb that,
nonetheless, "the FAA will not allow us to complete Certificates of
Airworthiness with a known defect. The FAA will allow us to certify
the aircraft already on the assembly line for VFR only." Columbia said
in its statement that the production line will "grind to a halt" until
a fix is found and parts shipments are restored.

GARMIN SNAFU ALSO AFFECTS OTHER AIRFRAMERS

At Cessna Aircraft in Wichita, Kan., production has continued despite
the G1000 problems, Director of Corporate Communications Doug Oliver
told AVweb on Tuesday. "We anticipate a resolution from Garmin
literally any minute," he said. However, deliveries of single-engine
piston aircraft are suspended until the issue is resolved. "Mustang
deliveries were originally suspended as well," Oliver said, "but due
to its lower production rate its avionics systems were installed some
time ago, before the suspect batch was produced. This has, of course,
been confirmed through testing and approved by the FAA." Oliver said
he doesn't anticipate any impact on production at Cessna. At Diamond
Aircraft, spokeswoman Heike Larson told AVweb that production will
continue.
