From the FAA’s Accident/Incident Data System (AIDS), through its Aviation Safety Information Portal, as reported. The NTSB investigates accidents separately, and its record of an accident is the fuller one. The aircraft is matched to the registry by N-number and event date, checked against the reported make and model; the registry’s history has gaps, so older matches can be wrong. Compare the reported make and model.

What happened

The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.

On March 3, 2011, at approximately 1928 hours aircraft Bombardier Learjet LJ60, N660CJ, s/n 60-126, departed Fort Lauderdale international airport (fll) in route to toluca, Mexico (mmto). Upon reaching 25,000 feet the crew was cleared to climb to 41,000 feet. Shortly after, the right hydraulic low pressure light came on and about 10 to 20 seconds later the left hydraulic low pressure light came on. As soon as the second light came on, the crew decided to return back to fll airport. Also, at this time, the crew noticed that the hydraulic pressure indicator was showing a continuous decrease in pressure. The crew requested and was cleared to establish a holding pattern over the dolphin (dhp) VOR. The crew flew a holding patter for two hours to burn enough fuel to prevent an over weight landing. During this time, the crew reviewed the entire emergency checklist procedure and executed the emergency landing gear extension checklist. The crew returned to the airport and just before landing, as per the checklist, the crew turned the hydraulic pumps on which gave them enough hydraulic pressure to get the flaps down 20 degrees and use normal braking procedures. The aircraft was taken to the Bombardier facility at fll airport for maintenance. Bombardier technicians troubleshot the aircraft and found the left main gear actuator leaking hydraulic fluid. The actuator was replaced. Also, the left and right hydraulic pumps were replaced. The aircraft passed all the ground and flight operational checks and it was returned to service. A service difficulty report, control number 2011FA0000193, was submitted. After looking at all of the facts this is considered an incident related to a component failure and no further action is required.

As the FAA filed it

ON MARCH 3, 2011, AT APPROXIMATELY 1928 HOURS AIRCRAFT BOMBARDIER LEARJET LJ60, N660CJ, S/N 60-126, DEPARTED FORT LAUDERDALE INTERNATIONAL AIRPORT (FLL) IN ROUTE TO TOLUCA, MEXICO (MMTO). UPON REACHING 25,000 FEET THE CREW WAS CLEARED TO CLIMB TO 41,000 FEET. SHORTLY AFTER, THE RIGHT HYDRAULIC LOW PRESSURE LIGHT CAME ON AND ABOUT 10 TO 20 SECONDS LATER THE LEFT HYDRAULIC LOW PRESSURE LIGHT CAME ON. AS SOON AS THE SECOND LIGHT CAME ON, THE CREW DECIDED TO RETURN BACK TO FLL AIRPORT. ALSO, AT THIS TIME, THE CREW NOTICED THAT THE HYDRAULIC PRESSURE INDICATOR WAS SHOWING A CONTINUOUS DECREASE IN PRESSURE. THE CREW REQUESTED AND WAS CLEARED TO ESTABLISH A HOLDING PATTERN OVER THE DOLPHIN (DHP) VOR. THE CREW FLEW A HOLDING PATTER FOR TWO HOURS TO BURN ENOUGH FUEL TO PREVENT AN OVER WEIGHT LANDING. DURING THIS TIME, THE CREW REVIEWED THE ENTIRE EMERGENCY CHECKLIST PROCEDURE AND EXECUTED THE EMERGENCY LANDING GEAR EXTENSION CHECKLIST. THE CREW RETURNED TO THE AIRPORT AND JUST BEFORE LANDING, AS PER THE CHECKLIST, THE CREW TURNED THE HYDRAULIC PUMPS ON WHICH GAVE THEM ENOUGH HYDRAULIC PRESSURE TO GET THE FLAPS DOWN 20 DEGREES AND USE NORMAL BRAKING PROCEDURES. THE AIRCRAFT WAS TAKEN TO THE BOMBARDIER FACILITY AT FLL AIRPORT FOR MAINTENANCE. BOMBARDIER TECHNICIANS TROUBLESHOT THE AIRCRAFT AND FOUND THE LEFT MAIN GEAR ACTUATOR LEAKING HYDRAULIC FLUID. THE ACTUATOR WAS REPLACED. ALSO, THE LEFT AND RIGHT HYDRAULIC PUMPS WERE REPLACED. THE AIRCRAFT PASSED ALL THE GROUND AND FLIGHT OPERATIONAL CHECKS AND IT WAS RETURNED TO SERVICE. A SERVICE DIFFICULTY REPORT, CONTROL NUMBER 2011FA0000193, WAS SUBMITTED.AFTER LOOKING AT ALL OF THE FACTS THIS IS CONSIDERED AN INCIDENT RELATED TO A COMPONENT FAILURE AND NO FURTHER ACTION IS REQUIRED.
