Learjet Heading Gyro 4000
Replace Troublesome Learjet DN-101 or
DN-104 Gyros
with
Dependable 10,000 Hour Sperry/Honeywell Gyros
The HEADING SYSTEM in your Learjet depends on an old gyro designed in the early 60's for the Lear-23. Unreliable and difficult to repair, these tired gyros contain components that have not been made for 30 years. Even late model 31s and 35s depend on this 40 year old design.
The DN-101 gyro
was designed to be incompatible with industry
standard
gyros, so replacements were not available. Learjet operators
were forced to rebuild and repair these old gyros over and
over again. Finally a modern plug-in replacement is
available.
The Insight Gyro 4000 is based on the best heading system in the industry, the Sperry/Honeywell C-14A. The C-14A rotors are equipped with long life bearings rated for 10,000 hours. Combining the C-14A with special interface circuitry in a compatible package, the Gyro 4000 is a plug-in replacement for the old JET DN-101 or DN-104.

Case
Study:
On
January 13, 1998, a Learjet 25B crashed two miles short of
runway 26 while attempting a second ILS approach to Houston
Intercontinental Airport in dense fog with visibility
reported to be less than a quarter mile. The aircraft missed
its first approach after the captain's directional gyro
flagged and the aircraft strayed 25 degrees left of the
final approach course. In addition, the aircraft had sticky
glideslope needles which had been previously squawked but
not fixed. Inexplicably, the experienced flight crew decided
to attempt a second approach. They didn't make it. [NTSB
