Wrong. Not true. Here is the exception. If you have an SOE and you do not have it removed, you can get another type in another aircraft, and that will dump the SOE off of your 1st type. The SOE is only for your 1st type rating. Example, get a lear type. It will have an SOE on it. You never fly the lear, and 6 months later, you return and get a Hawker type. When the Hawker type is issued, the SOE will get removed. If the examiner does not do it, the FAA will catch it before they send you your new certificate. At that point, even if you have never flown either aircraft, legally, you are allowed to go fly as PIC in either aircraft. Not all 1st types have an SOE. There is a list of requirements that will determine whether or not you will have an SOE. If you do get an SOE, there are other requirements that will determine whether or not it will be a 15 or 25 hour SOE.
