PIQUA, Ohio — June 7, 1994 — Hartzell announced today that its Top Prop™ four-blade propeller conversion for the Cessna 441 Conquest II has been approved by the Australian Civil Aviation Authority. Installation of conversion kits on Australian registered aircraft is proceeding apace. Official approval of the new system includes replacement of original Hartzell and McCauley three-bladed propellers with a completely redesigned Hartzell four-bladed prop including its B.F. Goodrich de-ice system.

The Civil Aviation Authority (CAA) – Australia is the equivalent of the Federal Aviation Administration in the United States. As such, it officially sanctions changes to original type certificates. Hartzell is pursuing official certification of the system from governing bodies in various additional countries operating Conquest IIs.

Hartzell’s Conquest II propeller conversion provides operators with significant reductions in cabin noise levels, increased acceleration, shorter take-off rolls, better climb and cruise performance as well as enhanced fuel burn and prop de-ice capabilities.

Hartzell Propeller Inc. is the world’s leading manufacturer of propeller systems enjoying 60 percent market share on turboprop airliners and 85 percent market share on corporate turboprops. The 76-year-old company is also well known for its design leadership having introduced the industry’s first full-feathering propeller for light twins, the first fully reversing propellers for corporate turboprops and the industry’s first composite structure blades.
