initiated certification efforts for its MT 7-blade on the
King Air 300 series in 2023.
Martin Albrecht, vice president of MT-Propeller,
highlighted the following advantages for King Air 300
series operators and passengers flying with the 7-blade
propeller system:
= General performance improvement (8% take-off
& climb)
= No propeller speed restrictions on ground while
operating in low idle
= Lower ITTs at high altitude, allowing a top speed
increase up to 6 KTAS or longer engine life
= Unbeatable aesthetic ramp appeal
= Significant cabin noise and vibration reduction
= More ground clearance for less blade tip erosion
and FODs due to a smaller diameter
= Nickel-cobalt leading-edge blade protection for
superior resistance to erosion and damage
= No life limitation; they are repairable in case of
FOD
MT-Propeller Vice President Martin Albrecht was at King
Air Gathering in March with the recently certified 7-blade
Whisper Prop installed on a King Air 350 also featuring
Blackhawk’s XP67A Engine+ Upgrade.
