M403V Fan Blade Scanner
The automated in-service inspection of aero-engine fan blades is a key component of aircraft safety designed and manufactured by engineers from Tieval and implemented on most major aircraft.
In 1996 engineers from Tieval developed the first fully automated ultrasonic inspection system to detect sub-surface cracks in wide-chord fan blades. The self-calibrating and auto-sentencing system was introduced as a mandatory inspection on Rolls Royce RB2-11 fan blades.
In 1996 the original M401 system was introduced as a mandatory inspection on Rolls Royce RB2-11 535 E4 and 524 G&H fan blades.
In 1999 new versions, the M401V and M403V systems were introduced for the inspection of International Aero Engines V2500 fan blades.
Many of the early systems are still in operation after many years with the M403V being the only system currently acceptable for use on V2500 fan blades.
Currently M403V fan blade scanners are located in England (1), China (2), Germany (3), Hong Kong (2), Japan (1), Malaysia (1), Spain (1), Turkey (1) and the United States (3) with all systems supported under TiCare calibration and maintenance contracts.
It is not possible to manufacture new M403V systems and we await introduction of the inspection process for IAE V2500 on the M403T fan blade scanner.
