The MEGA experiment at LAMPF is designed to search for the rare decay {mu} {r_arrow} e+{gamma} with a branching ratio sensitivity of 4x10{sup {minus}13}. The detector consists of an electron spectrometer (a set of low-mass MPWCs and two barrels of scintillators) and a photon arm (three-layer pair spectrometer) in a 1.5-T solenoidal magnetic field. The experimental design maximizes rate capability, retains large solid angle, and suppresses the background to below the experimental sensitivity. In the summer of 1992, the MEGA collaboration successfully finished whole-system tests and got 163.6 million {mu}{r_arrow}E+{gamma} candidate events by using the electron arm and two of the three photon pair spectrometers. The status of the data analysis will be described.
