- History of Flight:
On December 28, 2025, at about 1125 local time, an Enstrom F-28A, N520H, registered to a private individual out of Carneys Point, New Jersey, and an Enstrom 280C Shark, N280MG, registered to M&M Charter LLC out of Mountville, Pennsylvania, were both destroyed when they were involved in a mid-air collision in Hammonton, New Jersey. The pilot onboard the F-28A sustained serious injuries, and the pilot onboard the 280C sustained fatal injuries.
Both pilots were known to each other and locals. They flew together on weekly bases.
According to flight-tracking history, on the day of the accident, at about 0950 LT, the 280C departed Vineland–Downstown Airport (28N) Vineland, New Jersey, and proceeded northeast towards Hammonton Municipal Airport (N81), Hammonton, New Jersey. The flight lasted 7-8 minutes. At 1124 LT, the 280C was observed departing N81 and proceeding southwest before it disappeared from coverage. Only two data points were recorded, one at 1124:39, and the second at 1124:56. The second data point showed the helicopter at 600 ft, 65 knots groundspeed, a vertical rate of 250 feet per minute (fpm), and on a heading of 231.9°.
According to the same flight-tracking history, the F-28A departed Vineland at 0950 LT (same time as the 280C) and proceeded northeast towards N81 along with the first helicopter. Unlike the first helicopter, at 1125:04, the F-28A was observed at 650 ft, an unknown groundspeed value and vertical rate, and on an unknown track heading, and in the general vicinity of the 280C.
- Pilot Information:
Unknown.
- Aircraft Information:
The first helicopter, serial number 325, was manufactured in 1975. It was a three-seat helicopter powered by a Lycoming O-360 engine.
The second helicopter, serial number 1135, was manufacutred in 1978. It was a three-seat, single-engine helicopter and featured a three-bladed MR system that was powered by a turbo-charged Lycoming HIO360-E1AD engine rated at 190 horsepower at 2900 rpm.
- Wreckage and Impact Information:
(1) F-28A:
The F-28A came to rest upright and was not consumed by a post crash fire. The wreckage was mostly intact, but sustained heavy impact damage. The main rotor blade assembly and tail rotor remained attached to the helicopter following the collision. The tail rotor separated on ground impact.
(2) 280C Shark:
The 280C Shark came to rest inverted and was consumed and destroyed by a post crash fire.

(4) Area Forecast Discussion:
Area Forecast Discussion National Weather Service Mount Holly NJ 630 AM EST Sun Dec 28 2025 .SYNOPSIS... High pressure over the Northeast slides offshore later today. A warm front extending out from low pressure moving into the Great Lakes will lift north through the region tonight, followed by a strong cold front Monday afternoon. High pressure briefly returns on Wednesday, then several weak cold fronts will pass through the region into the end of the week. && .NEAR TERM /THROUGH TONIGHT/... Northwesterly flow aloft will continue to overspread the region through today, gradually weakening with rising heights as a ridge axis initially centered over portions of the Ohio Valley shifts eastward into our area. Tonight, rapid height falls and enhanced southwesterly flow aloft will begin to overspread the region ahead of a strong upper-trough approaching the region. At the surface, high pressure initially centered over the Mid- Atlantic will gradually shift east through the day as low pressure initially over the Midwest shifts east into the Great Lakes. A warm front will lift through the region overnight tonight. High clouds will continue to overspread the region into this morning, with low clouds working in from west to east this afternoon. The combination of background ascent from the approaching trough and additional lift from the approaching warm front will lead to light precipitation overspreading the northern half or so of the area beginning during the mid to late afternoon hours. Precipitation chances will be greatest along and north of I-78 (60-80%), and decrease as you go south from there. There will only be a 20-40% chance of a few showers for the Philly metro and south. Temperatures look to top out in the mid 30s to near 40 northwest of I-95, and the low-mid 40s southeast, with southern portions of the Delmarva and far southern NJ potentially approaching or breaching 50. As light precipitation overspreads the area, temperatures this evening into the first part of the night look to be near or below freezing across northern areas. Forecast soundings indicate this below freezing surface layer will be quite shallow, with a significant warm nose aloft. Therefore, precipitation type looks to be either freezing rain or rain depending on surface temperatures. Confidence is high that portions of the Lehigh Valley northward into the Poconos and adjacent areas of northern NJ will experience a period of freezing rain during the evening and into the early overnight hours. Outside of these areas, temperatures should be above freezing for the duration of any precipitation, so rain is expected. Overall precipitation amounts look light, but for areas that see freezing rain, hazardous travel conditions are expected. In terms of ice amounts, confidence has increased enough in a glaze of ice for Lehigh and Northampton Counties in PA and Warren and Morris Counties in NJ to expand the areal coverage of the Winter Weather Advisory to include them. For Carbon and Monroe Counties in PA, amounts have trended up slightly, and we now anticipate many locations to see a tenth to perhaps two tenths of an inch of ice accretion. The primary forecast challenge with this event is that temperatures will bottom out early in the evening and begin to rise from there as warm air advection begins with the approaching warm front. The areal extent of below freezing surface temperatures during the evening and overnight hours remains somewhat in question. A brief period of light freezing rain is not entirely out of the question for areas south of the current advisory, but if this were to occur it would likely be quite brief with marginal and rising temperatures. As the warm front lifts through the area during the overnight hours, temperatures will rise areawide. Temperatures are likely to rise above freezing areawide during the pre-dawn hours. Any remaining light freezing rain will change to plain rain during this time. There will likely be a brief period where the majority of the region is precipitation-free prior to daybreak Monday. && .SHORT TERM /MONDAY THROUGH TUESDAY NIGHT/... Warm front will be well north of the area Monday morning, resulting in the area being in the warm sector ahead of the approaching cold front. Low pressure passes north of the area, and this will drag that cold front through the region Monday afternoon. There should be a lull in the precipitation early in the morning, then showers develop in the late morning ahead of the approaching cold front and then taper off from west to east in the afternoon with the passage of the cold front. Temperatures ahead of the cold front will warm into the upper 40s in the southern Poconos, and in the low to mid 50s north and west of the Fall Line, and in the mid to upper 50s in the Delaware Valley and southern New Jersey and in the low 60s in Delmarva. CAPE values will be minimal ahead of the front, but 0-6 km Bulk Shear values will be 60-70 kt. Cannot rule out a rumble of thunder or some showers producing wind gusts up to 50 mph with the passage of the front. The pressure gradient tightens ahead of the cold front, and south to southwest winds will increase to 15 to 20 mph with gusts up to 30 mph in the morning, then behind the front, winds turn west to northwest with gusts up to 40 mph in the afternoon. The strongest winds develop Monday night and Tuesday, generally at 20 to 30 mph with 35 to 45 mph gusts. Gusts will be as high as 50 mph in Carbon and Monroe counties, where a Wind Advisory may be needed. If wind gusts continue to trend higher, a Wind Advisory may be needed for at least southeast Pennsylvania and New Jersey. Temperatures Monday night drop into the teens in the southern Poconos and mid and upper 20s elsewhere with single digit to low teens wind chills. One thing to watch out for is the potential for untreated wet surfaces to freeze Monday night. Winds should be strong enough to dry the roads out before temperatures drop below freezing, but it still may be a concern. Winds diminish late Tuesday and Tuesday night. Dry and cold with highs in the low to mid 30s Tuesday and lows in the 20s Tuesday night. && .LONG TERM /WEDNESDAY THROUGH SATURDAY/... Overall, the Long Term period will feature below normal temperatures. Several cold fronts will pass through the region, with reinforcing cold air moving into the region. The first cold front will pass through the region Wednesday night through Thursday, followed by another one Friday night through Saturday. Some light snow is possible with the passage of each front, but significant widespread accumulations are not expected. Highs will mostly be in the 30s with lows mostly in the 20s, except for Friday night when lows could be in the teens. && .AVIATION /12Z SUNDAY THROUGH THURSDAY/... The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG, KILG, KMIV, KACY and surrounding areas. Today...A mix of VFR and MVFR to start, with ceilings lowering to prevailing MVFR 16-21Z. Light rain expected after 19-21Z for KRDG and KABE. A few showers possible for the I-95 terminals after 20Z, though the chance is only 20-30%. Wind generally south- southeast around 5 kt. Moderate confidence. Tonight...IFR ceilings expected. Light rain could linger until around 02-03Z for KRDG and KABE. There is around a 20% chance for FZRA at KABE and less than a 20% for KRDG. South wind 5-10 kt. LLWS is possible at all terminals between 06-12Z. Moderate confidence. Outlook... Monday...Sub-VFR in SHRA through early afternoon. SW winds 10 to 15 kt with 20 to 25 kt gusts, turning W in the afternoon and increasing to 15 to 20 kt with 30 to 35 kt gusts. Monday night through Tuesday...VFR. W-NW winds 20 to 30 kt with 35 to 40 kt gusts. Tuesday night...VFR with diminishing winds. Wednesday...VFR. Wednesday night through Thursday...Sub-VFR possible in light SN. && .MARINE... Northwest winds over the ocean waters have diminished to 10-15 kt, with seas diminishing to just under 5 feet. Given this, have cancelled the Small Craft Advisory for New Jersey and Delaware Atlantic Coastal zones this morning. Northwest winds will remain around 10-15 kt this morning, shifting to southwesterly this afternoon. Overnight tonight, winds will again increase to 15-20 kt, with gusts to 25-30 kt. Seas 2-4 feet today will increase to 4-7 feet tonight. A Small Craft Advisory has been issued and will be in effect starting at 1 AM for all Atlantic Coastal waters as well as the Delaware Bay. Outlook... Monday...SCA conditions in the morning, then gales develop in the afternoon. Winds abruptly shift from SW to W-NW behind the passage of a cold front in the afternoon. VSBY restrictions in showers. A stray thunderstorm possible in the afternoon. Monday night through Tuesday...Gale force winds expected. Tuesday night through Wednesday...SCA conditions likely. Thursday...Generally sub-SCA conditions. && .PHI WATCHES/WARNINGS/ADVISORIES... PA...Winter Weather Advisory from 6 PM this evening to 2 AM EST Monday for PAZ061-062. Winter Weather Advisory from 3 PM this afternoon to 4 AM EST Monday for PAZ054-055. NJ...Winter Weather Advisory from 6 PM this evening to 2 AM EST Monday for NJZ001-007-008. DE...None. MD...None.
