G1000 Production Delays

Well, folks have been on other EFIS makers about delivery times ... now it's Garmin's turn, and Columbia is feeling the pain.

From Aero News Net:

Columbia Furloughs 'Hundreds' Due To Avionics Shortages

Tue, 14 Aug '07

ANN has confirmed that a large percentage of the Columbia Aircraft manufacturing work-force was laid off Monday, due to the reported lack of critical avionics components needed to finish the aircraft. "Nearly 300" staffers were notified Monday that they were furloughed until components of the Garmin G1000 glass panel system were delivered in sufficient quantity to re-start the production line.

Garmin recently notified Columbia of an inherent problem in the AHRS (Attitude, Heading & Reference System) of its G1000 integrated avionics system that will delay shipments of the Primary Flight Display used in the Columbia 350 and 400. The problem limits aircraft operations to VFR only and causes an inability for Columbia to issue a Certificate of Airworthiness to customer specifications for delivery.

A Columbia staffer noted that other manufacturers were also reporting problems in getting necessary deliveries of a critical component of the G1000 and that they were in the "same boat" as Columbia.

A Columbia statement reports that, "The resultant supply chain stoppage and business interruption is forcing Columbia Aircraft Manufacturing to furlough a portion of its direct workforce as the production line grinds to a halt until the issue is resolved and parts shipments commence. Customer Care, Factory Service Center, Sales, Marketing and Engineering will continue to provide the same level of support during the interim period until parts shipments enable production to begin."

Columbia officials learned of the problem from Garmin last week after other aircraft manufacturers reported attitude failure modes within the Primary Flight Display. The chief concern is that the avionics supplier is unable to definitively confirm when the problem will be resolved or when parts shipments will resume to Columbia. According to Garmin, all G1000 Primary Flight Displays manufactured on or after May 1, 2007 are suspect.

"This latest supplier-driven interruption is very frustrating," said Columbia President Wan Majid.

"Our recovery plan was masterfully executed earlier this year and deliveries have been proceeding on target. In fact Columbia has delivered 220 aircraft in the past four quarters - our best performance in company history. However, 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."

Majid confirmed that Columbia furloughed nearly 300 employees from its manufacturing facility. He also stated that it is possible that the Company will have to furlough additional employees if Garmin is unable to resolve the issue and resume component shipments quickly.

"Unfortunately, this problem is completely out of our control. I am deeply troubled to have to once again ask our valued employees to make this type of sacrifice as the result of supply chain issues. We will do everything in our power to resolve the situation as quickly as possible, but unfortunately I am not in a position to commit to a timeline at this point," Majid said. The Company is in constant contact with Garmin management and is supporting their efforts for a quick and proper solution.

Just last month, Columbia announced a healthy second quarter for the high-performance aircraft manufacturer, having delivered 55 new Columbia 350 and 400 aircraft in the second quarter of 2007, more than double the number delivered during the same period in 2006. While the Columbia's 2007 delivery pace was ahead of the figures posted in 2006, company officials cautioned that comparing 2006 to 2007 could lead to misconceptions.

"Early 2006 was very challenging for us and our second quarter deliveries in particular were severely hampered by a freak hail storm that delayed delivery of a 66 aircraft," said Columbia President and CEO Wan Majid. "That said, our deliveries are right on plan for 2007, and sales demand has been strong through the first half of the year."

Despite strong sales activity, supplier issues have brought a number of aircraft manufacturers to a virtual standstill or necessitated delays in aircraft production schedules... and a number of them were associated, also, with avionics. Eclipse's switch to a new vendor for its AVIO avionics suite, and the redesign of that system several months ago, cost the company a number of months in production delays.

The Garmin delays, if widespread, may affect quite a few manufacturers and create shortages throughout the GA industry, as the G1000 has achieved a high OEM adoption rate among such companies as Cessna, Diamond, Mooney, Piper and others.

ANN is looking into this issue and its effect on other manufacturers. We expect to update this report as soon as we can contact affected parties during normal business hours, later today.
 
My goodness somone other than #$% has new product delays and problems? :eek:
Lets crucify them :rolleyes:
 
What part?

They don't mention what the critical part is, or who makes it.

I wonder if the same part is used by the experimental EFIS guys?

Since electronic parts aren't made to Mil-specs any more, I also wonder if the experimental guys use the same part to a lower specification (a.k.a. rejects to the higher level specification.... :) ...)

I'm guessing a gyro sensor...

Welcome to the world of electronics manufacturing and the ripple effect. Supplier cannot supply Garmin- perhaps single source of chip- scary but no choice sometimes and Garmin cannot supply Columbia.

The airframers might want to have 2 choices for glass. I know it would be more work but when you have to shut down the line and tell workers to stay home, it is the lesser of two evils. Stuff like this can and has ruined companies.

The quote from Garmin says it is the AHRS. IIRC, didn't Chelton have a similar problem?
 
Inside the AHRS...

Yes, ...but I bet it's a single, critical component inside the AHRS... anyone know about the supply of solid state gyro sensors world-wide?

Milt I know who you are talking about. The difference is Garmin does not lie about the problems. They did not say that the orders were shipped then to find out it would be a month until I saw it. Nor do they ship product without working software and expect you to wait a year to get it to work. BIG Difference! It's been a year and I still do not have the software to run my autopilot.

I think this raises a bigger question on how the A(D)HRS work and the differing architecture. It'd be great to know what's going on under the hood, so to speak.

I have used several MEMS gyro based inertial systems in my day job. Most use Analog Devices gyros. We have found them to be good components and have not heard of any flaws in them.

The fact that they can trace it to a specific date leads me to believe they changed from one component to another at that time. If it were just a software change, they could have reverted to the old software. The performance of AHRS systems is particularly dependent upon the characteristics of the noise and bias produced by the gyros. If the new components had different specs from the old, perhaps it was sufficient to cause bad performance.
