Narrative:

On approach (vectors) to myl; mccall; identification; NDB runway 34. ZLC assigned a sebound vector to cross iom NDB at 11000 ft and cleared for the approach. Due to a late descent from ATC and our lack of familiarity with the procedure; resulted in crossing the NDB at 12000 ft MSL; 1000 ft higher than assigned. Also; after crossing; the procedure turn requires to remain within 10 NM of the NDB; we completed the procedure turn within 12 NM. The captain had received NDB training in the simulator; this was my first exposure to an NDB approach. Although the flight was never in an unsafe position; NDB training should be required by the FAA and provided during recurrency training. Companies should be responsible to train flight crews in NDB approach procedures when assigning flts to airports served only by an NDB approach.

Title: CITATION C550 FLT CREW HAS A DEV DURING AN NDB APCH TO MYL.

Narrative: ON APCH (VECTORS) TO MYL; MCCALL; ID; NDB RWY 34. ZLC ASSIGNED A SEBOUND VECTOR TO CROSS IOM NDB AT 11000 FT AND CLRED FOR THE APCH. DUE TO A LATE DSCNT FROM ATC AND OUR LACK OF FAMILIARITY WITH THE PROC; RESULTED IN XING THE NDB AT 12000 FT MSL; 1000 FT HIGHER THAN ASSIGNED. ALSO; AFTER XING; THE PROC TURN REQUIRES TO REMAIN WITHIN 10 NM OF THE NDB; WE COMPLETED THE PROC TURN WITHIN 12 NM. THE CAPT HAD RECEIVED NDB TRAINING IN THE SIMULATOR; THIS WAS MY FIRST EXPOSURE TO AN NDB APCH. ALTHOUGH THE FLT WAS NEVER IN AN UNSAFE POS; NDB TRAINING SHOULD BE REQUIRED BY THE FAA AND PROVIDED DURING RECURRENCY TRAINING. COMPANIES SHOULD BE RESPONSIBLE TO TRAIN FLT CREWS IN NDB APCH PROCS WHEN ASSIGNING FLTS TO ARPTS SERVED ONLY BY AN NDB APCH.
