John, did you get any info from Garmin regarding this?:
And, do you know if they make the AHRS themselves?
-----------------------------------------------------
Garmin G1000 Problem Affects GA Deliveries
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." Garmin spokeswoman Jessica Myers told AVweb
that the problem does not need to ground any airplanes. "We have not
placed any limitations on operation of the aircraft," she said on
Tuesday evening. "Day VFR, night VFR, day IFR, night IFR" all are
unrestricted, she said. "We are working as quickly as possible to
determine the cause of the problem and what the fix will be," she said.
"But I do not have a time frame." A service advisory is being prepared,
the company said. The glitch has occurred only in G1000 primary flight
displays manufactured on or after May 1, 2007.
Columbia Lays Off 300, Cites Garmin G1000 Issue
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. "This latest supplier-driven interruption is
very frustrating," said Columbia President Wan Majid. "We simply cannot
continue to complete and deliver new aircraft without the functionality
and reliability that customers demand. Unfortunately, this means that we
have no alternative but to furlough portions of our workforce until the
issue is resolved."
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. "We view this as a mere blip," she said. "We're not stopping
production, and we have inventory on hand with unaffected units to
complete current customer deliveries." Garmin is being "very proactive"
about the problem, she said, but it's possible that "customer deliveries
might be affected by a week or two" before all is back to normal. At
Hawker Beechcraft, spokesman Mike Turner said the problem has "minimal"
impact. Deliveries of Beechcraft G36 Bonanzas and G58 Barons are on hold
for now, but production is not affected, he said. At Mooney Aircraft in
Texas, spokesman Dave Franson said the interruption of G1000 deliveries
will have little immediate affect. "We have inspected the G1000
components we have on hand and believe that we have a sufficient
quantity of acceptable units to sustain our current delivery schedule
for approximately two weeks," Franson said. "We will continue to work
closely with Garmin during this situation and will keep our customers
advised through direct communications and updates on our Web site."

Garmin has known and failed to address (up until now) the pricing
disparity between the alternative EFIS top dogs. Chelton, OP
Technologies, GRT and Avidyne for the Experimental market.
We sat through a three plus hour presentation on Garmin product
placement, future development, vertical integration and a price
reduction. One friend who had just purchased a GNS530 was rewarded with
an immediate $600 back for attending. Gift Certificates which must be
converted within 72 hours covered their entire product line. I think
Paul was impressed with the $2275 price for a complete 496 hand-held.
They are now fully integrated with HITS coming soon.
Weather/Radar/ADS-B/Traffic and with the remote GCU 476 pad, you can use
the alpha-numeric keys just like the Flight Management Systems in our
big birds to create flight paths. At the NWEAA flyin, the cutey at
Columbia said that feature was only available on Columbia "certificated"
aircraft. Now it is available for Amateur built too. They have worked
with Tru-Trak and STEC for three-axis servo control. They have added
checklists, W&B and engine analyzing for LOP operations.
If they move the price point some more, they could become a complete
integrated competitor. They are not priced for the steam gage crowd or
for old fogeys with weak hearts. The price is known to create heartburn
in some customers.

PS, it's kind of strange how Garmin views this as a very minor
thing and is not placing any operating limitations on the systems,
when we've seen in the past that manufacturers did. Funny how
having a huge market share makes you a little sensitive to
taking that plunge.

Garmin makes their own components which are TSO approved and warranted
on the Certified units. The G900 uses the same components. Certified
equipment causes higher pricing.
When a failure occurs, the symbol generator places a big red x over the
item which forces the operator to resort to "Dare I say, a steam gage".
Cirrus uses them and Garmin wants certificated manufacturers to select
their own solution. For the G900, they do not make a recommendation.
They do hold most of the component cards and have been a bit snooty
about coming down and placing in the Chelton price point arena. This
may bode well for greater competition. The G900 comes with Dual
Nav/Com/ILS/GPS which uses two 530A 16watt output transmitters. That is
far stronger than the SL30.

PS - I am going to task Garmin to expand your website review of the
430/480 comparison and to add the 530 and G900 to the mix. It would be
great to get a side by side comparison on HITS, Terrain, ADS-B, Weather,
Traffic and Radar. With the million dollar Evolution and high end EFIS,
someone things there is money to spend out there. I have a hard time
just digging with the pitch fork to find my lost pony.
