Fieldstruck power lines/transformers on approach to rwy 28R in heavy fog and crashed 1/2 mile east of the arpt, the 2 POB suffered fatal injuries, the acft was destroyed, other circumstances are unknown. (.19) on April 15, 1999, at 0518 hours pacific daylight time, a Beech 36, N7706R, collided with eucalyptus trees and power transformers and crashed on a city street near an industrial park adjacent to the Montgomery Field Airport, San Diego, California. The airplane was on an ILS instrument approach to runway 28R when the accident occurred. The airplane, owned and operated by the pilot, was destroyed during the impact sequence and subsequent ground fire. The private pilot and his passenger, the sole occupants, sustained fatal injuries. The personal flight was being conducted under 14 CFR part 91 of the federal aviation regulations. The flight originated at calexico, California, at an unknown time. Instrument meteorological conditions prevailed at the time of the accident. At 0506 hours, the pilot originally contacted the federal aviation administration (FAA) southern California terminal radar approach control (socal TRACON) at 6,500 feet while en route from calexico to Montgomery field. During this and subsequent contacts with TRACON the pilot used the aircraft call sign N3930F. The pilot requested weather information and was told to contact San Diego radio. At 0509, the pilot was issued clearance to enter the San Diego class b airspace. At 0512, he was issued an IFR clearance to the airport and subsequently cleared for the ILS runway 28R approach at 0515. At 0518, the air traffic controller asked 30F (the call sign used by the pilot instead of N7706R) if he was receiving the glide slope satisfactorily, and the pilot replied "affirmative." The controller then advised the pilot to contact the Montgomery advisory frequency, since the control tower was not operating at this time. At 0519, the controller issued a low altitude alert for the pilot 1/2 mile east of deoro intersection, which is the outer marker for the ILS approach. Two witnesses reported hearing a loud explosion and witnessed the streetlights go out following an electrical power failure at 0518. The first witness said that due to the dense fog in the area, he could not see the wreckage until he was within 4 yards of it. A ereview of the FAA records on the pilot indicates that the pilot's medical certificate was administratively denied in July 1994. (.4)the pilot contacted fss and requested weather at several local San Diego airports. He was told to expect low IFR conditions with visibility less than 1/4 mile in fog and indefinite ceilings of 100 feet. The pilot then obtained a clearance to enter the class b airspace using a fictitious call sign. He requested and was issued an IFR clearance to the airport, and was later cleared for the ILS runway 28R approach. Prior to issuing the approach clearance, the controller asked the pilot what his intentions would be when he made the missed approach. The pilot replied that he would want radar vectors for a second approach. Numerous times on the approach the controller either asked the pilot if he was receiving the glideslope satisfactorily, or told him his position and what his altitude along the approach segments should have been. The controller issued two low altitude alerts; the final one at the outer marker where the airplane was observed 300 feet low. Recorded radar data showed that the airplane was consistently below ATC assigned and charted minimum descent altitudes for most of the approach. The airplane coolided with trees and the ground about 1 mile short of the runway. Two ground witnesses reported hearing a loud nosie and began looking for the source of the noise. They almost ran over the downed trees and the burning aircraft wreckage before acquiring it visually due to the dense fog. None fo the pilot's personal logbooks or aircraft records could be located to establish his instrument currency, although the pilot's daughter stated that he flew fairly frequently. A postaccident examination of the airplane revealed no abnormalities in either the engine or the airframe. The day before the accident the same airplane had been obserced intering class b airspace and landing at a controlled field without an ATC clearance. (-23)the aircraft wiht one pilot and one passenger crashed on a road 1/8TH of a mile from the approach end of runway 28R at myf. Both occupants were killed in the crash, the aircraft was demolished by a PST crash fire. No other persons were injured on the ground. The wx was IMC with less then a quarter mile vis with 100' ceiling obscured. The pilot was given the wx via ASOS approxiamtely 45 prior to the accident. No mechanical abnormalities were found during the post crash exmination of the wreckage that could have contributed to the accident. The pilot's medical and airman certificate had been revoked in 1994 by AWP-7. No further actions will be taken.
