Duncan Robertson in the UK has been working with the Light Aircraft Association (LAA) to gain approval for the Krybus/Hickman Lycoming conversion. Happily the LAA are being particularly helpful and have suggested that approval may be granted on the basis of "satisfactory in-service experience."
To achieve this Duncan needs to compile a credible database of conversions, time in service and any issues that have been observed with the conversion.
If you own or fly a Jungmann with this popular engine/cowl conversion, would you mind completing a copy of this document: HKENGINE-MOUNT-RECORD.doc and forwarding it to Duncan at
With any luck this will make the conversion available for anyone in the UK to use.
