Overview
The Learjet 31 is a twin engined business jet, manufactured as the successor to the Learjet 29 and produced between 1988 to 2002. It combines the fuselage and engines of the model 35/36 with the Longhorn wing of the 28, 29 and 55 models. It has capacity for eight passengers and two crew.
The first Learjet 31 flew in May 1987 and FAA certification was received in August 1988. Powered by two rear mounted 3,500 lbf Honeywell TFE731-2 turbofans, the 31 has a flight ceiling of 51,000 ft and good runway performance. Delta fins on the lower rear fuselage improve stall characteristics.
On early serial numbers, there is 30 cubic ft of luggage space inside the 12 ft long cabin. Later units incorporated an externally loaded aft fuselage locker.
The improved 31A and 31A/ER are later production models introduced following the acquisition of Learjet by Bombardier. The 31A/ER is an extended range variant with a higher maximum take off weight and greater fuel capacity. The first 31A gained FAA certification in July 1991 and entered service on 15 August. A new interior with increased headroom was introduced in 1995 while in 2000 take off and landing weights were increased and FADEC was added. Production ceased in 2003.
FAA approves Butler for replacement Learjet standbys

Butler has designed the retrofit installations to minimise customer impact and down time, and the replacement digital altimeter conveniently replaces most existing two-inch standby altimeters.
This cost-effective upgrade of Chronos digital clocks with USB chargers adds superior, FAA-approved functionality to the flight deck with minimal impact to the instrument panel.
