Since Aviation Partners announced in October that it would begin accepting orders for its drag-reducing blended winglets for the Dassault Falcon 900 series, the Seattle-based modification specialist has tallied firm commitments to equip at least 10 aircraft. Award of the STC is expected next month. Once approved, the $575,000 modification can be retrofitted to existing Falcon 900s. It is now factory installed on the Falcon 900LX, the latest 900 variant.
