Maintenance and Accessories Overhaul

The SEMAN, being a maintenance organization recognized nationally and internationally, expands its maintenance capabilities by implementing accessory workshops in which it performs the inspection, testing, maintenance, repair and overhaul of hydraulic components, fuel, dynamics, propellers, shovels and Ventaneria of aircraft which demand great professionalism, counting for that purpose with the authorizations that of the DGAC. Next, we present the accessories workshops that the SEMAN-PANAM has.

WORKSHOP OF HYDRAULIC COMPONENTS

The workshop has the capacity to perform Overhaul, Inspection, disarming and testing of servos and hydraulic pumps of fixed wing and rotary wing aircraft. It has a bank that has the ability to test and regulate the hydraulic components, has a dual system A and B that simulates the working pressure of the helicopter. Performs functional test of the servo main and simple actuators, cut valves and hydraulic pumps, whose working pressure is 0-5000 PSI, using a pressure of 2250 PSI to rule out leaks, and hydraulic motor for testing the different hydraulic accessories : Pumps, Actuators, Valves, Dampers, Servos, Flight control, Landing gear, PCU.

FUEL COMPONENTS WORKSHOP

This workshop has the capacity to perform overhaul, inspection, disassembling, assembling and testing of the fuel injectors applicable to helicopters and aircraft PT-6 turbines, fuel injectors applicable to turbines T-53, T-56, JT3D, J-85, Fuel Controls and Governors applicable to the helicopters BELL 412, BELL 212, and all the fuel controls applicable to turbines PT-6, J85.

Overhaul, repair, general maintenance and testing of the different accessories applicable to the opposed motors such as the servo injectors pumps, distributor, injectors, manifold and fuel cells applicable to the helicopters BELL 212, 412, HUEY II, UH1H, aircraft C-130 and A-37. This workshop has different types of benches to perform tests of different capabilities, such as:

FUEL CONTROLS TEST BENCH

This bench is able to test and regulate flow-driven benches with capacity of up to 10,000 PPH and 30 horsepower for the repair of different controls, governors, pumps, and fuel regulators. It simulates all conditions as if they were with the engine running. Simulates (RPM, Throttle Angle, Air P3, Flow of the main pump to the control, the counter pressures applied by the injectors to the control).

 INJECTORS TEST BENCH

This bench has the capacity to test up to 1000 psi of the primary and secondary system of the different injectors applicable to the power plants. Functional tests can be performed to accurately determine Flow angle, Fuel Nozzles Spraying, Overhaul and servicing of the entire line of injectors PT6, GARRET, T53, and J85.

SERVOINJECTOR TEST BENCH This bench provides us with a fuel flow, to adjust carburetor float levels, automatic mix control calibration, fuel consumption test measurements, carburetors calibration and fuel injection system used by light and heavy aircraft. Overhaul tests can be performed on fuel pumps, Bendix pressure carburetors, Continental fuel injection system, Bendix Continental Altitude Compensation, pump-driven blade-type engine, additionally verification and adjustment of float levels at all types of carburetors. Performs the following Tasks and Operations: (Servo injectors, Injectors, Fuel Controls, Carburetors, Honeywell – Woodward – HR Textron – Parker)

  • Inspection
  • Repair
  • Functional Tests
  • Operational Tests
  • Overhaul

DYNAMIC COMPONENTS WORKSHOP
