Old Bar, Mid-North Coast, NSW
At a recent Greater Taree Council Meeting, the Honorary Secretary of
the Old Bar Heritage Airstrip Committee, Mr. Tony Ryan, was approached
by a community group in request to help reduce the annoyance of low
flying aircraft in the vicinity of the strip and Farquhar Park. The
concerns revolve around low level orbits for extended periods in close
proximity to the picnic area in the park and around residences in the
area.
Mr. Ryan has requested and encourages all pilots (not just trikes) using
the facility to be mindful of the expectations of others and to avoid
flying low (500ft) over identified gathering areas unless taking off or
landing. Once airborne, as with any facility or aerodrome, pilots should
vacate the area to prevent any continuous noise becoming a concern to
residents and others recreating in the area.
The committee fought for over six years to have this strip re-opened,
and do not wish, as volunteer managers and maintainers, to give any
small number of opponents ground on which to complain. All responsible
members of any aviation discipline are more than welcome to use the
facility.
Board Meeting
The next HGFA Board Meeting will be held over the weekend 17-18 April at
the Tullamarine Motor Inn in Melbourne. All members are welcome to attend.
At this meeting we will see the induction of the new with some of the
current Board remaining for 2004-2006. They are:
Rohan Grant (TAS), Rohan Holtkamp (VIC), Mark Thompson (WA), Kathy Robinson
(WA), Carla Pierce (VIC), Bill Moyes (NSW), Andrew Polidano (NSW), Hakim
Mentes (VIC) and Stewart Dennis (ACT).
Any members with items they wish discussed at the meeting should correspond
with the Board representatives so that they may add it to the agenda.
Parachute Repacks
Some points noted by Chris Fogg after attending one of Angelo
Crapanzano's (Metamorphosi Chutes) Clinics are worth reproducing here:
1. Repacks should be conducted at three month intervals. Angelo indicated
that a chute recently packed has a far greater deployment speed and
reliability than one that has been stowed for longer than three months. Even
if you do not do a full repack you should at the very least check the bands
holding the lines. We witnessed perished rubber bands on almost all the
chutes that were deployed during the clinic.
2. The preferred sequence of events during deployment is bag, bridle, lines,
chute inflation. Many of the chutes we witnessed came out all at once. This
super loads the chute during the inflation and causes significant shock
loading to the system and presents greater chance of entanglement. Packing
should be managed in a manner that avails the sequenced deployment of the
bag followed by the bridle followed by the lines followed by the chute
inflating. Angelo demonstrated techniques of folding the chute so that a
single gore would pull open before the remainder of the chute, thereby
pushing the chute open, rather than having it pulled open by the forces of
air surrounding the chute during descent. (The forces of air around the
chute are the main factor that makes the chute open - pulling it open which
generates much more shock than pushing it open from within.)
3. Many of the chutes we saw (particularly for the paragliders) were
attached to the harness bridle by threading the chute lines through the
bridle loop. Angelo indicated that this may lead to material burn during
inflation due to the friction created during the opening shock. We were
advised by Angelo to use a metal shackle to make the join.
4. Positioning the parachute on the harness is a critical factor in
accessing the chute for deployment, especially during a spin. Angelo noted
that the side of the harness is his preference. Although this has the
limitation of being accessible to one hand it is more likely that the hand
in question will be able to reach and pull the handle than if the handle is
positioned on the shoulder, back, bottom or front of the harness.
5. The thumb should be used to grip the handle, sliding it through the
inside of the loop rather than tugging at it with the fingers. It is a
smoother and more powerful action to push the thumb into the handle opening
and push outward with the deployment bag than it is to grip with the fingers
and tug at the handle.
6. The handle length is a critical feature to safety in deployment of the
chute. The longer the handle straps the slower and greater the effort
required to deploy the chute. There is also more potential for the handle to
interfere with the successful deployment of the chute.
7. Velcro is a no-no. If possible find an alternative method to securing the
closures of the chute other than with Velcro. Velcro can be abrasive to the
lines and material. It can also stick in the wrong place while the chute is
being deployed. At a minimum make sure that the Velcro on the handle is
female (the fluff side) and that the male part is sewn to the harness.
8. A chute should be retired after three years. The material starts to
weaken thereafter, even when stowed in the best possible manner. At the
clinic we witnessed chutes that were sixteen years old!
9. Ultraviolet protection should be incorporated into the packing of the
chute by placing foil around the deployment bag. Even when stowed into the
harness, ultraviolet can penetrate through to the chute, lessening its
overall lifespan.
UP Paraglider Safety Notice
Safety Notice 12/02/04
In the light of Peter 'Putte' Peterson's fatal accident (further info on
the DHV Drachen-und Gleitschirmforum > Sicherheit) on a Gin Gliders
Boomerang 3, we would like to urgently remind all UP Targa and Trango Race
pilots to adhere to the given maintenance intervals. 'Putte's' tragic
accident should be a reminder that pilots may too often fail to follow the
prescribed maintenance instructions.
Line Material
Both the UP Targa and the UP Trango Race are equipped with Aramid(R)
lines from Edelrid (series 7000 and 8000) with a diameter of 0.6, 0.9 and
1.1mm. These lines are all unsheathed and must therefore be treated with
extra care and attention. Gliders equipped with these lines are in no way
suited for acro flight! One year check interval, UP Targa and UP Trango
Race. The UP Targa and the UP Trango Race must have the lines checked at
least every year, or after 100 hours (whichever occurs first). This
mandatory check can be done here by UP Europe. We are also ready to check
your equipment at closer intervals should your particular usage of the
equipment warrant it (flying in extra-abrasive environments, performing acro
on the wing, etc).
For your own safety we highly recommend that you follow the prescribed
service intervals and that you treat your equipment with the care and
attention that it deserves!Team UP Europe

Accident Reports
I must stress that all accident reports received and published here (and
even those not published here) are not and have never been meant to
apportion any blame or fault upon any person; they are reproduced only in
the interests of safety and to ensure that we may all become better pilots
and find more satisfaction, less grief and frustration in pursuit of our
flying passions.
No 1.
Pilot: adv PG
Experience: 57 hrs total, 6 hrs last 90 days
Glider: DHV 2
Pilot Injury: fractured bones in left foot
Glider Damage: nil
Location: inland soaring site
Conditions: 6-8kt headwind, mod turbulence
Description: Pilot launched and after experiencing mainly sink headed for
the LZ. When just below the tree line of the paddock, flying into a
headwind, the wind dropped and ground speed increased. When at about 20ft
agl the pilot encountered lift and rose to about 35ft and was now a fair way
into the LZ paddock and unable to land straight ahead due to a gully and
trees. The pilot did a 90 degree right hand turn and landed heavily after
the flare on a sloping rock.
Comments: Inland thermal flying at its nastiest; no doubt the decrease in
headwind and possible tailwind was caused by thermal activity and perhaps
some wind shadow or turbulence behind the trees. All landings in thermal
conditions need to be treated with particular care and forethought.
"Options" is the most important word in a soaring pilot's vocabulary. When
you run out of options, an accident or incident is far more likely to occur.
Landing in areas bounded by or behind trees needs extra care taken for wind
shadows, mechanical turbulence and thermals triggering. Choose an area to
land where these phenomena are less likely to occur. If that is not
possible, then have some options should you find yourself with extra (or not
enough) height. Inevitably, as thermal pilots, we will all sooner or later
find ourselves landing tailwind into what should be the predominate wind
direction. With options up your sleeve you are more likely to be able to
reassess the whole approach as it proceeds, to make any safe changes
available for a safe landing.
No 2
Pilot: int HG
Experience: 600 hrs total, 14 hrs last 90 days
Glider: adv HG
Pilot Injury: minor abrasions
Glider Damage: upright, LE, sail damage and glass tip
Location: coastal soaring site
Conditions: not provided
Description: Pilot was keen for a fly after not flying for a month or so and
had inexperienced wire assistants with no other pilots available. When
assistants advised they had no weight or input on the wires the pilot
launched and the left wing immediately dropped. The glider turned and
impacted rocks below launch downwind.
Comments: Poor communication and inexperience of assistants appear to be the
main cause of this incident. Clear and concise instruction of what is
required by any assistant should be given, and conduct of a 'dry run',
especially with inexperienced persons, should always be undertaken. Use of
clear and concise language ("CLEAR") and what is required when those
instructions are given should be covered in any practice and briefing. On
giving the "clear", the briefest of moments should be taken to ensure that
the wings are in fact level with no input from assistants. (These comments
reproduced from a similar incident reported in November '03 Soaring
Australia.)
No 3
Pilot: restricted HG
Experience: 18 hrs total, 4 hrs last 90 days
Glider: int HG
Pilot Injury: sprained wrist
Glider Damage: uprights and basebar
Location: coastal soaring site
Conditions: not provided
Description: Pilot was first to take off and did so well. Pilot turned 180
degrees at end of first beat. Following close to the hill the pilot entered
into a gully and misjudged downwind speed and failed to turn away from the
terrain. Landed downwind in prone.
Comments: Lack of experience and recognition of airspeed vs. ground speeds
left the pilot with no OPTIONS. Restricted pilots should always maintain a
safe and conservative distance from terrain, commensurate with their skills,
until such time as skills, ability, knowledge and experience lets them enter
situations which they can handle with ease and confidence.
No 4
Pilot: restricted PG
Experience: 22 hrs total, 3 hrs last 90 days
Glider: PG DHV 2 paramotor specific
Pilot Injury: cracked vertebrae
Glider Damage: nil
Location: airstrip
Conditions: 3kt headwind, nil turbulence
Description: Pilot was attempting to launch with a home built trike base
when the left rear wheel lifted and they did not counter with the brake. The
trike base rolled around the cage at low speed and the pilot did not touch
the ground. Pilot had previous spinal injuries, hence the use of the trike
base.
Comments: 20 hours is not enough experience for paramotor flying, certainly
not for use of trike bases. The engine may have been under powered for the
job, with the added weight of the trike base. Also the wing was unfamiliar
to the pilot. As the pilot had previous spinal injuries the vertebrae may
have been weakened, and in such cases they may suffer from osteoporosis.
There was surprise that such a slow, low/no impact incident as this caused
any damage at all, but for the previous condition.
No 5
Pilot: FEI PG and passenger
Experience: 500 hrs total, 30 hrs last 90 days
Glider: tandem PG
Pilot Injury: nil
Passenger Injury: sore neck
Glider Damage: nil
Location: coastal soaring site
Conditions: headwind, nil turbulence
Description: Tandem pilot and passenger had landed after a successful tandem
instructional flight. On deflating the wing the canopy pulled the pilot and
passenger off balance and the passenger fell head first into sand.
Comments: Take care; the flight is not over until you are out of your
harness. Be prepared, as the canopy will still require your attention even
during deflation. Despite the lack of seriousness of the injury, the FEI
insisted that the passenger remain calm and still while assistance was
called in order to prevent any further injuries.
