Textron Aviation’s Service Bulletin SB525C-56-01 introduces a critical modification for the Cessna Citation CJ4, designed to reduce moisture incursion around the windshield and cockpit side window frames. While compliance is not mandatory, it has become a key factor influencing resale value and marketability in the pre-owned CJ4 market.

The market places a premium on maintenance history and service bulletin compliance, particularly for modifications that address long-term structural concerns. SB525C-56-01 improves sealing and corrosion protection around the windshield and cockpit windows, leading to notable pricing differences between compliant and non-compliant aircraft.

Our market data suggests that aircraft without SB525C-56-01 compliance are still selling but at a discount, often reaching $600,000 or more, due to buyer concerns over potential future maintenance costs and downtime. However, an aircraft with a scheduled SB525C-56-01 appointment at a Textron-authorized service center can still command pricing comparable to compliant aircraft. With service slots currently booked into 2026, securing an appointment has become highly valuable. Buyers recognize the advantage of purchasing an aircraft already in the queue, avoiding long wait times while ensuring compliance. Additionally, having a scheduled SB presents a prime selling opportunity, as the aircraft will already be at a Textron service center, facilitating pre-purchase inspections and minimizing downtime for both the buyer and seller.

For Cessna Citation CJ4 owners planning to sell, scheduling SB525C-56-01 compliance in advance is a strategic move. Even if the modification is not completed before the sale, a scheduled appointment enhances marketability and strengthens negotiation leverage. Sellers who proactively secure a service slot can better position their aircraft for a strong resale price.
