Gear Won't Retract

[hharney]

Rod
Here is the suggestions from the service manual. You did not mention if you had tried these so I will start by posting this and see if it helps. There are limits to the doors that need to be activated before the system will allow the gear to retract. These limits are a safety so that the gear does not damage the doors during retraction. If it works on the ground up on jacks then when in the air it does not work there is a problem with alignment of a limit switch that is failing because of the air pressures during flight that are not found on the ground test.
