Hello, Would appreciate comments with regard to the use of Dual PMags on a BA Prop Metal 2 blade(Hartzell) on the Thunderbolt IO 390 or similar. Although building a 14, would gratefully appreciate comments from any RV type with a similar prop, engine, and ignition system. Note my fuel lnjection system is a FM 150.
Completing the build in the U.K. under the auspices of the LAA.
Looking for current operational experience of the above configuration to help justify the initial U.K. experimental operation of the Hartzell 2 blade metal BA prop on the 390 with dual P Mags.
Initial proposal intends to have prop limitations similar to those originally applied to the IO 360 with additional full dynamic balancing and also additional annual inspections of the prop to establish or minimise that no adverse damage is apparent due to unwarranted vibration harmonics. If possible also make annual vibration analysis of similarly operated props on a comparison data basis?
Currently the LAA require the prop to have undergone the required certification vibration testing as required under the US AC, this has not been undertaken in the above configuration, hence the request for operational experience of such operations from within the US RV fleet which may have a similar configuration.
