TransDigm to buy Jet Parts Engineering and Victor Sierra Aviation for $2.2B
TransDigm will buy Jet Parts Engineering and Victor Sierra Aviation from Vance Street Capital for about $2.2 billion in cash. The purchase of two proprietary aftermarket/PMA suppliers— which together generated roughly $280 million in 2025 revenue— broadens TransDigm's aftermarket/MRO footprint and accelerates PMA consolidation.
