Welcome to Propulsion International (PI)

Propulsion International

Propulsion International provides low cost turbine engine maintenance plans and credit arrangements for business aircraft operators and commercial fleet operators.

Savings occur at major maintenance events, at each repair, and with each hour flown. Enrollment can occur at anytime in your engine’s life cycle.

Group Maintenance Plans (GMP) lowers the cost of maintenance 15% to 20% as compared to Time and Material (T&M) invoicing and protects from unforeseen costs.

Backed by Honeywell Aerospace, a TPE331 engine enrolled in GMP results in a serialized maintenance reserve account within Honeywell, solidly providing the security of a manufacturer’s program.

All maintenance is performed at your choice of participating Honeywell authorized service centers worldwide. Performed under the guidance of Honeywell more high quality/new parts are installed, ensuring the highest level of engine quality and reliability.

Operators experience full maintenance coverage at a price below their current Time and Material invoicing, without the risk of cost overruns, unscheduled repair costs, and price inflation. Payments are made based on hours flown and maintenance is accomplished without additional operator cost.

PI’s solution results in; lower aircraft operating costs and predictable level payments.
