[Guyana] JAGS Aviation unveils Sky Truck
DECEMBER 24, 2014

    The M28 Model 5 Skytruck at the Guysuco Hangar yesterday afternoon.
JAGS Aviation, a member of the BK Group of Companies held a ceremony yesterday to welcome their Poland-made, M28 Sky Truck to Guyana, at the GuySuCo Hangar at the Ogle International Airport.

The M28 Skytruck is the newest addition to the JAGS Aviation fleet now owned by BK. The aircraft was described as a “game changer” as it will boost passenger and cargo transportation. The aircraft has seating capacity for 20 persons and is valued at US$4M and will accommodate chartered flights.

Manager of JAGS, Briony Tiwari reminded the gathering yesterday of her promise of “high quality” additions and investments. This promise was made when JAGS introduced their brand new Cessna Grand Caravan 208B EX in August. She continued that it was not “empty words” but a promise that has come to fulfilment. She also promised more “quality” additions to the fleet in the future.

Minister of Public Works, Robeson Benn welcomed the entry of the aircraft and told the gathering yesterday that the aircraft will be a game changer and as the fleet widens it will strengthen links with persons from the hinterland such as miners and Amerindians. He also said that because of the aircraft’s capabilities and design, soldiers and engineers in Guyana would be able to expand their knowledge.

He said that the government stands by and supports the efforts to expand the civil aviation sector and said that persons should take an example from the Tiwari family as he congratulated them.

Shadow Minister of Public Works for A Partnership for National Unity, Joseph Harmon said that the addition of an aircraft to the aviation sector is an “occasion for celebration”. However, he pointed out that management of the aircraft would be a challenge.

Harmon’s comments were followed soon after by the Minister of Tourism, Industry and Commerce, Irfaan Ali who stated that the transformative move would not have been possible if the development of the Ogle Airport was not undertaken by the government, which he said, stands as a testimony of the government’s vision for expanding the aviation sector. He further said that the private sector cannot expand without the boldness of the Government.

Chairman of the Guyana Civil Aviation Authority, Hugh Denbow said that it brought great pleasure to learn about another aircraft. He also made several New Year’s resolutions saying that the authority will try to reduce or eliminate aircraft accidents and continue safety, security and management training.

According to a press release from JAGS, the M28 Model O5 Sky Truck is a twin engine, high-winged cantilever monoplane, made with metal structures and is best suited for passenger and cargo travel.

The twin vertical tails and a tricycle non-retractable landing gear, features a steerable nose wheel which would assist with short, unprepared runways where hot or high altitude conditions may exist.

The release further stated that the M28 has many characteristics such as short takeoff and landing capability, perfect flight handling at low airspeeds, high useful load, mission versatility, unpaved airstrip operation capability, easy access through rear cargo door, fitted with a hoist for cargo loading and relocation inside the cabin.

The high-wing arrangement aids in protecting the engines and propellers against damage when operating from unpaved airstrips. Easy and quick conversion of the cabin interior configuration and low operating cost.

The PZL M28 Skytruck is a Polish STOL light cargo and passenger plane, produced by PZL Mielec, as a development of license-built Antonov An-28. Early licence-built planes were designated PZL An-28. The maritime patrol and reconnaissance variants are named PZL M28B Bryza ("sea breeze").

Design and development

The Antonov An-28 was the winner of a competition against the Beriev Be-30 for a new light passenger and utility transport for Aeroflot's short haul routes, conceived to replace highly successful An-2 biplane. The An-28 is substantially derived from the earlier An-14. Commonality with the An-14 includes the high wing layout, twin fins and rudders, but it differs in having a new and far larger fuselage, plus turboprop engines. The original powerplant was the TVD-850, but production versions are powered by the more powerful TVD-10B, with three-blade propellers.

The An-28 made its first flight as the An-14M in September 1969 in the Ukraine. A subsequent preproduction aircraft first flew in April 1975. Production of the An-28 was then transferred to Poland's PZL Mielec in 1978, although it was not until 22 July 1984 that the first Polish-built production aircraft flew. The An-28's Soviet type certificate was awarded in April 1986.

PZL Mielec has become the sole source for production An-28s. Basic variant, not differing from the Soviet one, was designated PZL An-28 and powered with PZL-10S (licence-built TVD-10B) engines. They were built mostly for the USSR, until it broke up. The plane was next developed by the PZL Mielec into a westernised version powered by 820 kW (1100shp) Pratt & Whitney PT6A-65B turboprops with five-blade Hartzell propellers, plus some western (BendixKing) avionics (a distinguishing feature are exhaust pipes, sticking out on sides of engine nacelles). Designated the PZL M28 Skytruck, first flight was on 24 July 1993 and it is in limited production, mostly for export (39 produced by 2006). The type received Polish certification in March 1996, and US FAR Part 23 certificate on 19 March 2004.

Apart from the Skytruck, PZL Mielec developed a family of militarized light transport and maritime reconnaissance planes for the Polish Air Force and Polish Navy in the 1990s, with original PZL-10S engines, named PZL M28B in the Air Force and Bryza in the Navy. From 2000, newly produced M28Bs started to be equipped with five-blade propellers as well.

PZL M28 Skytruck

It is a twin-engined high-wing strutted monoplane of all-metal structure, with twin vertical fins and a robust tricycle fixed landing gear, featuring a steerable nose wheel to provide for operation from short, unprepared runways where hot or high altitude conditions may exist. The M28 is best suited for passenger and/or cargo transportation.
  • Short takeoff & landing (STOL) capability
    Excellent flight handling at low airspeeds
    High useful load, mission versatility
    Unpaved airstrip operating capability
    Easy access through rear cargo door, fitted with a hoist for cargo loading and relocation inside the cabin
    High-wing arrangement for protection of engines and propellers against damage when operating from unpaved airstrips
    Easy and quick conversion of the cabin interior configuration
    Low operating cost
    PT6 engines of inverted configuration for efficient protection against foreign object ingression owing to inertial separators installed inside air inlet ducts.
While of conventional design, one notable feature of the An-28 is that it will not stall, due to its automatic slats. An engine failure that would usually induce the wing to drop 30° is combated by an automatic spoiler forward of the aileron that opens on the opposite wing, restricting wing drop to 12° in five seconds.
Operational history

176 An-28s and M28s in all variants were built in Poland by 2006. Most numerous users are former Soviet civil aviation and the Polish Air Force and Navy (about 25 as of 2006), smaller numbers are used by the Polish civil aviation and in the USA, Nepal, Colombia, Venezuela, Vietnam and Indonesia.

On 4 November 2005, a Vietnamese Airforce M28 crashed in Gia Lam district, Hanoi. All three crewmembers died.[1]

On 12 February 2009, The weekly periodical Air Force Times reported that the Air Force Special Operations Command (AFSOC) would receive 10 PZL M28 Skytrucks in June 2009.[2] These aircraft carry the U.S. Air Force model design series (MDS) designation of C-145A Skytruck.

On 27 October 2010, an Indonesian Police Skytruck, registration #4204, crashed in the District of Wangga, Nabire, West Papua, Indonesia after carrying aid for victims of natural disasters in Wasior, West Papua. All five crewmembers died.

The C-145A’s primary role is to support U.S. Special Operations Command’s Aviation Foreign Internal Defense mission to assess, train, advise and assist foreign aviation forces in airpower employment, sustainment and force integration. Secondly, the C-145As provide the theater Special Operations Commands a light mobility capability. These mission sets are conducted by AFSOC’s Combat Aviation Advisors.

The C-145A is a twin-engine, high-wing aircraft with twin vertical fins and a non-retractable tricycle landing gear capable of short takeoff and landings to unprepared runways. The C-145 is reconfigurable to support both airland and airdrop of cargo (max 2,400 lbs) and personnel, casualty evacuation, combat search and rescue, humanitarian assistance and disaster relief operations. The C‑145A can carry a maximum of 16 passengers or 10 combat rigged paratroopers. Maximum cargo weight is 5,000 lbs, or up to four litter patients. Missions can be conducted to prepared and semi-prepared airfields around the world.

The C-145A aircraft was originally bought to support the non-standard aviation mission in 2009. In 2010, Congress authorized the purchase of 16 light twin engine aircraft to support the AvFID mission. As a result, the C-145A was selected for this role. The aircraft has been continually deployed since March 2011. The Air Force Special Operations Warfare Center currently has 10 C-145As and is scheduled to receive its final six aircraft by April 2014.
