Incident Overview
During the takeoff roll, the right gear inboard tire blew out. Both right tires were subsequently destroyed by the forces of the takeoff roll. The aircraft continued the departure.
Hydraulic System Failure
While climbing through 19,000 feet, the right hydraulic system indicated zero pressure and zero quantity. As the flight progressed, during the approach to landing, the left hydraulic system depleted.
Landing and Brake Lock
After landing, the left brakes locked because the anti-skid system was inoperative due to the hydraulic failure. The aircraft came to a stop with the left brakes engaged.
Investigation Findings
Investigation revealed that no prior damage to the tire had been recorded. The operator's daily service inspection requires that tire pressure be checked with a tire gauge. Two additional blown tires had occurred during takeoff from the same operator's station within the preceding three months. Evidence of tire under inflation was discovered after the third incident.
