''Maintenance information is in the Equipment officer’s guide.''
{{Warning|The ultimate reference is the current version of the flight manual which takes precedence over anything written in this guide. This guide is not meant to be a substitute for the flight manual. The flight manual is kept in the CU folder in one of the cupboards in the workshop.}}
Rigging CU is quite easy and two people who know what they are doing can rig in 20 minutes. However, ASW19s are at heightened risk of rigging related accidents due to disconnected their controlsnot being self connecting, so make sure you have rigged correctly. If in doubt '''check with someone who knows how to do it'''. == Converting to CU == Read through the CGC conversion notes and the ASW19b flight manual. You must obtain permission from the duty instructor and the CUGC committee before you can convert. Standard requirements are: # At least 6 solos in a CGC Junior# Demonstrate a fully held of landing in a slippery glider like the Perkoz# Receive a full briefing These can vary with the instructors discretion. Ideally you can convert to the CGC Pegase FVV first, which is very similar and permanently rigged. Main points to consider from the CU conversion notes: * It is high performance and slippery. Speed control on approach is very important, especially with airbrakes that are less effective than on the 2 seaters and Junior.* Retractable undercarriage - don't forget to put it down!* Poor low speed aileron authority. This makes the aerotow ground run tricky, and is recommended to thermal above 50kts.
== Pre-rigging notes ==
Some basic rules and things to be aware of:
# Never rig the glider unless you are 100% sure you know what you are doing, . If you are unsure get help from an Instructor or somebody who is familiar with an ASW19;.# Don’t get distracted or interrupted during the rigging process, this is how you forget something;.# Alway do a full DI and positive control checks before taking the glider to the launch point;.# Always get a full briefing and read the flight manual before a conversion flight;.
# 60% of accidents caused by disconnected elevators happen on ASW19 or 20s, double check the elevator connections before flying.
== Parking the Trailer ==
CU lives in the western trailer park at GRL. As of Summer 2020, between LA and an older SHK glider. When parking, attach the hitch to the permanent ball in the parking location. Make sure the handbrake is left '''off'''. Lower the rear stabilisers until they take the tension.
{{warning|If moving CU and the trailer in winter, take caution not to dig holes in the ground as these will be hard to fix in the summer. If unavoidable, fill in any ground damage immediately.}}
== Rigging ==
You need at least 2 people to rig CU, but 3 is helpfulif you are not feeling strong or the wind is high.CU's wings are particularly heavy, and holding the root might be a challenge if you are not confident. Feel free to ask anyone in the trailer park to help you rig, they should be happy to help, but the usual etiquette is that you will then help them with their wings. Don't take advantage of people!
=== Preparation === # Unlock trailer at both ends and open.# Remove any boxes from the front of the trailer (these can get crushed when the lid opens).# Open the trailer lid fully from the back.# Remove trestles, ramp, ramp handles, etc. Be careful not to scratch the glider.# Lower Ensure the end of trailer is secured with the tow hitch attached to the permanent ball and the trailer if needed. Extend rear stabilisers taking the trailer legs tension to stop it from wobbling. This sets up the rear of the trailer at the correct height.# Remove carpet from wing tips and cover Cover trailer cornersand floor with carpet.# Attach Pull out the ramp to , ensuring the pins engage in the slots at the end of . Place the two securing bolts in the trailer, holes above these pins to stop the pivot jack at ramp popping out.# Secure the end should be ramp in the low '''upright (raised)''' position with using the wheel extended AWAY from the trailer sidered pin.# Move wings out horizontally to the edge of the trailerto provide more fuselage clearance.# Undo blue the strap that holds the tail down (this may not be attached when the trailer is parked). === Removing Fuselage === # Lift fuselage by the black handle strap around tail and slide it out of trailer (until the belly dolly reaches the end of the ramp. '''mind Mind the top of the fin as you come out, and be careful not to trip over the ramp.''')# Remove the strap though the fuselage, and tennis ballsand the tail strap. (Tennis balls may might not be installed when the trailer is parked).# Remove strap on Ensure the straps for the battery (behind your head when sitting in the glider) are clear of the space for the tailwing roots.
=== Connecting the starboard wing (right) ===
Always rig with the right wing first (this has the fork). Person 1 is the person in charge of the rig. # Person 1 2 lifts the wing tip and slides the wing out of trailer (. '''mind Mind the wing on the pins on the fuselage and on the edge of the trailer''').# Once fully out, person 2 1 lifts the root and carries out it clear of the trailer.# Person 2 rotates the wing90 degrees so it is perpendicular to the fuselage.# Rotate When ready, both people rotate the wing so that it is flat, and place ready to slide into the fuselage.# Person 1 places spar in hole in fuselage (. '''make Make sure that the fuselage doesn’t wobble''').# Slide Both slide the wing in (. '''make Make sure that the control rods slide into the holes and don’t catch on the fuselage'''). Person 1 may have to instruct person 2 on whether they need to move the wing forwards/backwards/up/down so that it slides in flush. Make sure the gap between the wing is uniform and about 3-5mm.# Once fully in, person 2 Person 1 places a trestle under just outboard of the tipsilver slide on the wing, person 1 being careful not to put the trestle on the aileron. Person 2 can relax.
=== Connecting the port wing (left) ===
Repeat as for the starboard wing, except place the trestle at the tip. Check again that the wing/fuse gaps are even and haven't changed with the second wing going in. See picture for recommended trestle locations.
=== Inserting the main pins ===
[[File:CU Main Pins.jpg|thumb|right|The main pins in, but not rotated and latched into place.]]
Inserting the pins should be a quick an easy task taking less than a minute, if they are not going in the wings are not level and not aligned correctly.Do not blindly force the pins in; take a moment to step back and assess if its not easy. Make sure you give your wing tip holder a rest if it is taking a long time!
# Person 1 removes a pin from green bag (they are identical). The orange bag This is stored under on the seat cushion when the glider is de-rigged, or sometimes in the plastic box. Make sure they are greased; if not, then apply a little from the grease tub with the red lid in the plastic box.# Person Look down the holes for the pins; you should be able to see if the holes line up or what needs doing to make them line up. Usually, person 2 lifts one on the port (left) wing tipneeds to lift slightly.# Person 1 inspects the pin holes, behind the seat in the spar, and gives instructions to person 2 whether to move the wing tip up/down so that the holes in each spar align/fwd/back. Check Keep checking that the both wings are flush with the fuselage, if not it may be necessary to move the wing tip forward/backward to achieve alignmentfuse.# Person 1 inserts Put the starboard pin into one of in first, all the holes as far as it will go (usually about half way)if you can.# Person 1 removes Repeat for the second pin and inserts it in the second hole fully. This may require some additional moving of the wing tip by person 2.# Person 1 then can push pin 1 fully in.# Rotate the pins so that handles meet, at the bottom and '''lock them in place with the safety catch halfway between the pins'''.
# Person 2 can now relax.
Some people have success putting the first pin in half way, then getting the second pin in, and returning to the first. Do this if you are struggling. We also have a white machined plastic rigging aid in the green bag. You can put this in the holes and rotate it to attempt alignment.
=== Lower the wheel and remove from dolly ===
# Lower the main wheel using the lever in the cockpit. Take the opportunity to check the tyre and wheel brake condition.
# Lower the jack using the long bar; take the tension off the pin, pull the pin out, then gently lower the ramp either way as is convenient. Don't move the lever towards the wing unless you are sure it is clear.
# Gently push the glider backwards to be clear of the the belly dolly.
=== Connecting the tail plane ===
This step can be done before moving the glider off the dolly if required.
# Collect the tailplane bolt, allen key and wire tool from the green bag.
# Push the wing root dollies to the back of the trailer, out of the way.
# Person 1 & 2 stand in the trailer at each end of the tailplane, which is attached to the roof of the trailer.
# Person 2 (at the back of the trailer facing forwards) supports the tailplane.# Person 1 (at the front facing backwards) pushed pushes the handle on the back support roof mount to his leftrelease the tail, making sure the support will tailplane doesn't drop and person 1 catches it so that it does not crash into anything.# Remove the tailplane from the trailer and avoid scratching the glider with itor tripping over the ramp.# Lower the tailplane onto the fin (putting the tailplane mount in the big square hole) and then push backwards firmly to lock in place.# Use the metal wire to pull back the small metal loop on the top of the tail plane, and place the bolt into the tailplane a do . Do the first few turns by hand to avoid cross threading, then tighten up with the allen key. Slot the wire lock into the closest bolt slot once it gets tight. {{Warning|Note that the metal loop is very fragile. If it gets damaged it will need cutting out of the tailplane, which is very expensive.}}# Tighten Return the bolt as far as it will go wire tool and then loosen one notch, allen key to the metal loop will fit into one of the cuts in the boltgreen bag.
=== Lower Connecting the main wheel controls ===
# Connect each control by:
## Pulling down the collar
## 2 x ailerons
# Ailerons and air brake controls can be accessed from the little panel behind the cockpit.
# Roll the connection around in your fingers and make sure it doesn't pop off when you gently pull it.
# Once controls are connected, close and lock the little panel. '''Make sure that the little panel is taped up securely with a wing tape, as the locking mechanism does not lock it fully.'''
{{Warning|Proper positive control checks are critical here.}}
=== Install total energy tube ===
=== Install Vertica (optional) ===
{{Warning|Status Vertica files are out of the vertica is UNKNOWNdate (Sep 2019), you are advised to use XCSoar on your phone.}}
# Vertia flight computer is kept in the CUGC box below the parachute room
# Mount the glide computer using the RAM x-grip mount in the centre of the instrument panel
# Adjust the positioning by slightly loosen the two screw handles, make sure NO INSTRUMENT IS COVERED BY THE PHONE, then tighten the two screws again
# Plug in the usb power cable. You may need an adaptorIn July 2020, a daisy chain of mini-USB, since the cable has an old micro -USB and USB connector-C adaptors are available.

[[File:CU ballast weights.jpg|thumb|right|Fitted ballast weights.]]
Ballast weights are stored in on the CUGC bottom shelf of the battery cupboard in the parachute room(next to the office).
# Check ballast requirements and remember the conversion between ballast weight and equivalent pilot weight (x2.5)
# Ballast weight weights go on a spindle in the nose# To gain access to the spindle, sit on the left hand side of the glider and apply full left rudder. Remove the nut (don’t and washer from the spindle. '''Be careful not to lose)these.'''# To You’ll need to add a the ballast weight you will need weights one by one. It is necessary to slightly close the canopyto slide each weight in.# Replace Carefully replace the washer and nut and secure . Check the the rudder cable is clear of the ballast stack of weights. Tighten the nut.
== Daily inspection ==
During daily inspections make sure that you check the condition of the glider’s skid. If the bottom foot is worn, the glider is U/S and skid needs replacing. Please see a picture of new skid for reference.
