Engine failure procedure in the G/A is as mentioned, deal with it as a F15 T/O.
Engine failure on approach can be a subtle and dangerous event. However, there are essentially two ways to deal with it. In IMC it is a mandatory G/A. At normal landing weights Vref F30/40 is more or less equal to V2 F15, therefore treat it as a F15 T/O for accel. In VMC some companies (and Boeing) allow the approach to be continued. In this event you must set G/A power, select F15 and accelerate to at least Vref +15 (sometimes known as the "High White Bug") +5. If at a later stage on the approach you decide to G/A, now the call will be for F1 as in the 1 ENG INOP approach and accelerate as per sched. Hope it never happens!
