Check list.
1. Reduce speed and select Flap10 Before starting descent.
2. Reduce MP at less than 1 imch per minute on descent.
3. Plan so as to achieve 1 and 2 to arrive in CCT at 120 kn or thereabouts.
4. Allow turbochargers to cool before shutdown
(If not your check pilot will swear at you and hit you).

All else is standard.

This is written by someone who has never flown a 404. Same SB who loves a cable tie perhaps

The Sydney seabreeze must have some adverse effects to brain cells.

Unfortunately I gave away my copy of the C404 POH many years ago, but I do not recall any advice from Cessna to "reduce speed and select flap 10 before starting descent", or such complex instructions re engine management. No flight engineer, so what attention would our pilot be paying to the outside world if fixated on manifold pressure?. Not saying that is is not worthy of some care, but really - less than an inch per minute? Is that done by use of a stopwatch or, in reality could we be trusted with general advice to gradually reduce it, rather than make rapid changes, and heed the other general advice pertaining to geared props: to keep them positively loaded until near landing?
That 'checklist' is more like a (misguided) instruction manual for student pilots. Hanging flap out before you need it is a baaad idea, not only from a cost perspective, but many airframes are less tolerant of turbulence with flap.
When operating any aircraft: time/drag = fuel = money, so whoever wrote that checklist was not flying in the real world..
However, we all know that older tech turbo charged engines do need gentle run down time. The more of that done while taxying in, the better, as air-cooled engines don't take kindly to idling while stationary on a hot day. The checklist-cum-how-to-fly book quoted above is a bit light-on with sound advice, but big on bullsh!t.

From the horses mouth.

PS: there is no such thing as a Flap 10 position, the selections are UP, T.O. & APPR and LAND.

...which also shows why the 'idling on ground for a few minutes after landing to cool the turbo' usually achieves the opposite of what those who advocate it intend.

Page 7-42 Engine Shutdown

After extended periods of ground engine operation above 1600 RPM or when the CHT indicator shows values within the upper half of the green arc, reduce engine power to between 600 and 800 RPM for a period of not less than 2 to 3 minutes prior to engine shutdown. This procedure is intended to reduce internal turbocharger temperatures and preclude the possibility of premature accumulation of carbon on the turbine shaft seals.

And after a long descent, approach, landing and short taxi at RPMs below 1600?

Hey All,

I am also looking for a 404 POH, if someone has one would they be able to send it to me?

Kind Regards

Hi all,
To once again open an old thread, does anyone have a Cessna 404 POH they could send me in soft copy?
Thanks in advance.

Think I’ve got a shiny C421C one… same donkeys? Can’t remember.

Ahhh memories!

The 404 all I remember is what a truck!

flyauskiwi; I`m currently in Japan, but will be returning to Australia in about a week. If you haven`t had any other replies by then, I`ll see what I can do.

For anybody interested: I have an original (hard copy) 1979 C404 POH in good condition available. First in with an offer, best dressed. PnP at your cost. QLD based. PM me if interested. (Also have B76 and B58 in vgc).
