I was plaaning to do my multi endorsement on the PA-30 Twin Comanche but it seems that the same rule applies to the Twin Commanche. This rule is a bit surprising considering that the earlier requirement was that the particular type should be registered (no valid COA condition earlier) in India.
I had a friend who got his endorsement on the Twin Commanche in June 2010. However, the COA had expired in 2006.
Any news on when this rule has been amended. Another source of further complications from DGCA.
