operations, a solenoid limits the pressure differential to 0.25 psi in order to ensure normal functioning of the door and emergency exit. The pressure differential at final cruising altitude will be maintained at 8.7 psi difference between pressure altitude and cabin altitude. A rate controller enables the crew to select the rate pressurization of the cabin within preset limits. The normal pressure relief valve will open at 8.9 psi differential pressure and the safety outflow valve will open at 9.2 psi differential pressure which is the maximum allowable differential pressure. Oxygen is contained in a pressurized bottle located in the dorsal fin of the aircraft. The use of oxygen is only required for emergency in case of depressurization of the cabin or contamination of the cabin air. Oxygen is always available for the crew and can be made available to the passengers manually or automatically. The oxygen storage cylinder has a capacity of 38 cubic feet and is stored at 1800 psi. An oxygen rupture disc will relieve oxygen pressure if the oxygen cylinder pressure reaches 2700 to 3000 psi. A green overboard indicator on the outside surface of the dorsal fin will be ruptured or missing to indicate that the rupture disc is not intact.

angle-of-attack of the aircraft. When the aircraft speed is 7% above stall, the stall warning energizes a control column shaker that produces a low-frequency buffet signal through the control column to warn the crew. When both angle-of-attack transducer vanes increase to 5% above stall, the pitch servo commands an aircraft nose down attitude. The force applied in the nose down direction is 80 pounds at the control wheel. When the angle-of-attack transducer vanes decrease below the stall point, the nose down command is removed. An angle-of-attack indicator translates signals from the stall warning system into visual indications of the aircraft angle-of-attack and allows the crew to monitor the proximity of stall caution zone. The indicator face is divided into green (safe), yellow (caution) and red (danger) segments.

straight taxi, takeoff and gentle turns. Primary steering mode allows up to 45 degrees angle of turn and is suitable for slow speed aggressive steering maneuvers. On aircraft equipped with variable authority steering, the steering authority varies with ground speed. The CJ610-6 engines fitted to the
Learjet 25 have very low inertia and accelerate rapidly. The time required to accelerate from idle to 100% RPM is approximately four seconds. This excellent throttle response enables rapid acceleration and precise power settings. Single engine performance is good with the single engine rate of climb approximately 1700 feet per minute at gross weight at sea level and a single engine service ceiling of approximately 21500 feet.

the variable volume engine driven pump delivers fluid under a pressure of 1450 psi to the system and static pressure is maintained at 1500 to 1550 psi. Over pressurization is prevented by a pressure relief valve which opens at 1700 psi. A pre-charged accumulator dampens and absorbs pressure surges. Two motor-driven shutoff valves will stop hydraulic flow to the engine-driven pumps in case of an emergency. The valves are controlled by the FIRE switch and activation of these valves are indicated with pinhead lights located in the cockpit next to the FIRE switch.

According to authorities, communication with the plane was lost 10 minutes after departure. The wreckage of the aircraft was found in the municipality of Los Tecojotes, and rescue personnel confirmed that all aboard were killed. From the lack of scatter of the wreckage, the aircraft is believed to have impacted at a vertical angle of over 80 degrees from horizontal.
