Landmark Aviation Receives STC to install Rockwell Collins Air Data Computer on Dassault Falcon 50

Tempe, Arizona, — Landmark Aviation today announced that it has received Supplemental Type Certificate (STC) approval for the installation of the Rockwell Collins dual ADC-87A air data computers on Dassault Falcon 50 aircraft.

“As a replacement for the existing air data computer, the digital ADC-87A provides greater reliability and makes the aircraft compliant to fly in RVSM (Reduced Vertical Separation Minimum) airspace,” said Dennis Mick, Landmark Aviation Engineering Manager. “While operators benefit from reduced maintenance costs, the ADC-87A also provides an upgrade path for operators requiring enhanced surveillance to operate in European airspace. The ADC-87A is compatible with modern display systems like the Collins’ ProLine 21 Integrated Display System.”

Federal Aviation Administration (FAA) certification was completed by Landmark Aviation’s Designated Alteration Station (DAS). Work will be performed at Landmark Aviation’s Springfield, Ill., maintenance, repair and overhaul center, a full-service aircraft center with more than 225,000 square feet of space providing airframe, engine, avionics, interior refurbishment and modification and paint capabilities. The facility is a Class 4 FAA certified repair station, and is also JAA (Joint Aviation Authority) and EASA (European Aviation Safety Agency) approved.

Landmark’s MRO business offers tip to tail maintenance and repair for all corporate aircraft, from a Beechcraft King Air to a Bombardier Global Express, at 11 facilities in the United States.
