Less than a year ago, two new CPCP maintenance task cards that require a detailed inspection of the horizontal spars and internal box structure were introduced by Dassault Falcon Jet.
Tasks 55-10-00-220-801 and -802 are new 2C requirements and are due on all out of production F50, F900 and F2000 with a non-composite H-stab. This would make them come due at the next like inspection if the aircraft is 12 years or older.
Also, task card 55-10-00-220-801, which is an internal DET inspection of the H-stab through the removed tip cap fairing, requires a video boroscope at least 13 feet in length that most shops do not have in their GSE inventory.
Here is a list of aircraft by serial number that have composite H-stabs but are not affected by this new requirement. Please check your aircraft for any deviation of this list.
