Dash 10

Increase your climb and cruise performance now! Retrofit your 690A, B, 840 or 900 Twin Commander with factory certified TPE331-10T engines and aircraft parts backed by Twin Commander and Honeywell.

The Dash 10T provides a noticeable torque gain at altitudes over the -5 engine.

The Dash 10T engine powered 690A test aircraft consistently demonstrated 300-310 KTAS cruise speeds at 20,000 feet, depending on aircraft weight.

(Performance data based on preliminary flight tests. 690A and B aircraft have been tested with similar performance improvements.)
