Rogerck Posted April 5, 2013 Report Share Posted April 5, 2013 We are having some work done on our 06 CTSW and it will be good time to check for proper engine alignment. The specified downward angle is 5 degrees and is easily determined using a digital angle meter. ( BTW, the LS down angle is 3.4 degrees.) My first question relates to setting up the 2.5 degree right thrust. Not sure what people have used as refenence points or tools to establish this angle. . IF the front of the cowling is perpendicular to the centeline of the aifrcraft, then a 2.5 degree offset would require the back of the spinner plate to be approximately 5/16 "closer to the cowling on the right side than the left (front to back). That's a fairly large difference and I'm not sure that most SW's have this kind of offset. A 2.5 degrees side angle is fairly significant (think of a 3d glideslope.) On the other hand, perpaps the cowl is fabricated to include the right hand and downward angles. Refer to section 3.3.7 of the attachment, Note . This would seem to suggest that the cowling has these offsets built in if its used to line up the engine. In summary, I have two questions: - what process have people used to set up the right thrust? - Does the cowling shape include both the right and downward angles? BTW, our CT has always required a fair amount of right trim for straight and level flight. If power is reduced the nose falls to the left, power increase nose turns right. See section 3.3.8 of the attachment for proper flight verification. We'd like to get this right.
