T55-L-714A
Honeywell T55-L-714A is a T55-family turboshaft in the 5,000-shaft-horsepower class for commercial and military helicopters. Honeywell technical material describes the T55 architecture with a seven-stage axial compressor and two-stage gas-producer turbine; its current T55 product page presents the 714C as a drop-in enhancement for the 714A and lists a 15,066 rpm output shaft. The structured shaft-power value is normalized to 3,728.5 kW from 5,000 shaft horsepower. Active status reflects current Honeywell support and upgrade compatibility for the 714A baseline, not a claim that new -714A production continues.

- Note
- Official Honeywell technical brochure identifies the exact T55-L-714A model, its turboshaft type and 5,000-shaft-horsepower class, and distinguishes it from T55-GA-714A and T55-L-714C; no aircraft installation or lifecycle claim is made here.

- Note
- Honeywell’s current T55 product page presents the 714C as a drop-in enhancement for the 714A and lists a 15,066 rpm output shaft; this supports current support and upgrade compatibility for the exact 714A baseline without asserting continued new -714A production.
